HEAVY-DUTY 1,2 & 3 PHASE ROTARY TAP SWITCHES POWER SWITCHES FOR INDUSTRY100 Thru 5000 Ampere, Single Phase100 Thru 2500 Ampere, Two or Three PhaseNON-LOAD BREAK 600 Volt, 60 Hertz AC 600 Volt DC
Types S1, T2 & T3 Heavy-Duty Rotary Tap Switches are complete units with escutcheon platesand appropriate safety handles. They are long operating life, low maintenance switchingdevices, specifically designed for the severe conditions of industrial use. They feature low oper-ating torque; high pressure line contact; flame retardant, non-tracking insulation; and precisionmade non-ferrous parts. All current carrying parts of 200 ampere switches and larger areheavy silver plated. Switches up to the 1000 ampere size feature glass fibre reinforced mold-ed bases for high strength, precision contact alignment, and light weight.
DUAL CURRENT RATING
Types S1, T2 & T3 Heavy-Duty Rotary Tap Switches are dual rated for both continuous andintermittent duty: Continuous/intermittent.
Continuous Current Rating is based upon a 40˚C temperature rise and a 40˚C ambient.Intermittent Current Rating is based upon a 40˚C temperature rise, a 40˚C ambient, a 50 percent duty cycle, and a one-minute integrating time.
SINGLE, TWO OR THREE PHASE
2000, 3000 and 5000 ampere Heavy-Duty Rotary Tap Switches are custom designed andmanufactured for each specific application. They provide the same fine materials, workmanshipand quality as the lower ampere switches and feature custom design, low operating torque,high pressure line contact, fabricated insulated bases, precision made non-ferrous silver platedparts. Along with the 800, 1200 and 1600 ampere switches, they have built-in rotor lubrica-tion systems.
All switches are supplied with escutcheon and handles. The handles have a provision for twopadlocks as a standard feature.

E CONSTRUCTION DETAILSDETENT-ACTION SWITCHES
Electroswitch Detent SwitchesElectroswitch Detent Switches are a heavy-duty design that is very versatile and enablesstandard units to satisfy a great variety of complex switching applications. They are modularin that several subassemblies are stacked together to form a rigid rugged device. Figure 1shows a cut-away view exposing the basic components.
OverviewThe mounting plate (1) connects a detent assembly (2) to one or more contact decks (3)and finally a position limiting stop plate (4). These assemblies are bolted together alongwith a steel shaft (5) and a handle (6).
The Electrical DesignThe Detent Switch contacts operate on the time proven reliable principle of knife switches –double-sided, double-wiping, spring-wiper blades closing on both sides of a terminal. This designis shock-proof and virtually bounce-proof. Figure 2 shows a typical contacting arrangement.
The Detent AssemblyThe detent assembly contains a specially designed star wheel and up to four spring-loadedball bearings providing snappy positive indexing. Spring return switches use a coil spring inplace of the star wheel/spring/ball bearing arrangement.
The Pull-to-Lock MechanismControl switches generally have positions both 45˚ left and right of the normal vertical position.The handle spring-returns to the normal position. The pull-to-lock mechanism enables an operatorto turn the handle beyond the left (normally TRIP) position to the 90˚ location, pull out thehandle and thereby lock the switch into this position. This precludes the possibility of someoneinadvertently closing a circuit-breaker when it is desired that it stay in the tripped position.
The Contact Deck AssemblyThe electrical parts are contained within sturdy phenolic moldings that provide individualinsulated compartments where all switching takes place.
An insulating barrier completes the contact deck assembly. The barrier not only separatesone contact assembly from another but alsoprovides a tight insulating compartment. Withthis construction there is no need to add adust cover.
Positive, reliable, maintenance-free operationresults from the double-sided, double-wiping, self-cleaning knife-blade moveable contacts.
The barrier next to the stationary terminals is clearly marked with numerals for Series 24 and 31 that correspond with the wiring diagrams.
Terminal screws secure the external wiring to the terminals.
Jumpering may be done right on the switch providing a simple and neat arrangement. Silver plated brass strap jumpers are available for adjacent contacts– either between adjacentcontacts on the same deck or the same terminallocation on adjacent decks. Wire and lug jumpersare also available. Jumpers are already suppliedassembled on the typical instrument switches,illustrated in this catalog, simplifying field wiring. All you need to do is connect the instrument leads and the line wires.
The Stop PlateThe steel stop plate assembly includes a steel stop arm that is connected to the shaft anda steel stop plate that contains tapped holes. Stop screws are inserted in the field to limitthe positions to the number and location desired. This externally adjustable position limitingfeature allows the use of standard switches for many customized applications. The limitscrews are supplied assembled for typical instrument switches.

Snap-Action SwitchesSnap-Action Switches use a design that enables them to combine a small number of basicparts to satisfy a wide variety of requirements for selector and control switching of power circuits. Standard switches built with this design for15-, 40-, 60 -, and 200-ampere capacitiesare listed in this catalog. However, the cataloged units merely indicate switching possibilities; wewill gladly recommend other combinations, based on our experience, for specific requirements.
The Electrical SystemThe electrical system comprises two or more stationary contacts (9)and one or more sets of movable contacts. These are pairs of spring-metal blades (8) that make high-pressure, low-resistance contact on both faces of the stationarycontacts while bridging two or more of these contacts. The stationary contacts fit in radialgrooves (12) in the rim of molded insulating disks (7), within which the movable contactsare carried on an insulated shaft (11). All “making” and “breaking” of electric circuits takesplace within the closed spaces between adjacent disks. Their quick-break action makes theseswitches particularly suitable for direct-current service. The ends of the stationary contactsextend outside the insulating disks and serve as connecting terminals (10 ). This one-piececontact/terminal construction minimizes series resistance and heating. Depending on currentrating and on-wiring requirements, the terminals may have tapped holes for connectingscrews or clearance holes for bolt connection of cable-lugs.
The Mechanical SystemThe mechanical system is designed to provide uniform high-speed “make” and “break”,regardless of whether the operating handle (1) is turned rapidly or slowly. Turning thehandle through approximately 120˚ in either direction winds a powerful coil spring (3).When this is fully wound, the indexing plate (4) is momentarily withdrawn from the lock-ing plate (5) by an eccentric cam. The drive-shaft and movable contacts then snap rapidlyto the next position. The indexing plate holds them until the spring-drive mechanism is againoperated. Transit time is about ten milliseconds.
AssemblyThe snap-drive mechanism, mechanism-cover (2), locking plate, mounting bracket (6),insulating disks, and back plate (14) are stacked on side securing rods (13) and boltedfirmly together to form a rigid assembly. The handle is keyed to the operating shaft andsecured by a screw.
Stationary ContactsNon-shorting (break-before-make) contacts are standard in all the ratings and circuits shown in this catalog.
Shorting (make-before-break) contacts, requiredin some special circuits, are available on order.
The “sweep” contact maintains the connection with the rotor through consecutive positions.
Moveable Contacts (Rotors)The simple, straight-across rotor bridges stationary contacts in the same insulating disk. It provides single-throw switching in Circuit 1 and double-throw switching in Circuit 6.
The right-angle-blade rotor provides a double-throw switching, with an intermediate OFF position, in Circuit 7.
A multi-fingered blade is combined with a single-contact blade to form a composite(double-deck) rotor that interconnects stationary contacts in adjacent disks. Suitableblade arrangements provide double-throw, triple-throw, or four-throw switching.
Insulating Disks (and Circuits)The insulating disks, molded of phenolic per MIL-M-14, have three functions. They hold thestationary contacts, they form enclosures that contain all making and breaking contacts, andthey provide both mechanical and electrical separation of switching sections.

E
Cam-Action SwitchesThe design principle allows the combination of a relatively small number of basic parts to sat-isfy a wide variety of requirements for selector and control switching in power circuits.
The Mechanical DesignThe switch features a modular design with switching decks (3) stacked with a detent mecha-nism deck (6), a mounting plate (12), and a handle (13). A steel shaft (10) couples thehandle to the operating parts. Two steel securing rods (11) are used to bolt the whole mecha-nism rigidly together. The basic parts and assemblies are shown below.
The Detent AssemblyThe detent assembly (6) consists of a spring-loaded detent block (7) with a roller cominginto contact with a notched detent wheel (8). This detent wheel provides the standard 45˚detenting as well as optional 30 ,̊ 60˚or 90˚detenting. The stop arms (9) are located underthe mounting plate. These limit the angular rotation to the desired number and location ofpositions.
The Contact AssemblyThe contact assembly (3) consists of a rigid thermosetting plastic housing, two sets of stationarycontacts (5), and two spring-loaded (16) movable contacts (1) held in cam followers (2).Floating on the shaft and held within the contacting chamber are two independent cams (4).The cams are notched to provide the contact “close” angles desired. The contacts are spring-loadedclosed and mechanically opened by the cam action to avoid sticking. The terminal screw (15)and pressure clamp (14) will easily accommodate stranded wire with lugs or solid wire, eitherwith or without lugs, compatible with switch size.
Contact OperationThe contacting consists simply of shuntingtwo isolated contacts to make a circuit. Two independent sets of contacts areplaced in each deck. The moving portion is spring-loaded to close the contact. Anotch on the cam is affixed to the operatingshaft allowing the moving contact to spring close, bridging the stationary contacts.
The movable contact (1) is spring-loaded (16) and held by the cam follower (2). It makesa circuit with the two stationary contacts (5) when the cam follower enters the notch in thecam (4).
Identically, the same thing is happening with the contact set on the right. This circuit is heldopen by the cam and will close when the notch on the second independent cam is rotatedaround and comes in proximity to its cam follower (the second cam notch is illustrated bythe dotted lines–the cam is underneath the other one).
We show the contacts pictorially to agree with typical detailed schematics and wiring plans. Thissimple system makes the switch contact arrangement, performance and location independent of the switching action required. The switching action is varied and controlled by the shape of the cams– allowing a virtually infinite number of combinations using a few standard parts.This simplicity and flexibility makes it easy for you to design your own switch – using familiarcontact language. You eliminate the worry, long deliveries, high costs, etc. normally associatedwith special switches.
Note: The terminal numbering consists of individual numbers for each terminal for positiveidentification.

All About TestingSwitches are tested in many ways to prove their capabilities and reliability. Electroswitchuses a combination of test methods to provide meaningful data for all applications. Theseinclude:
1. Cycle it mechanically until it breaks. This is usually an academic test since switches thatdo not switch electric power are not needed. An exception is a setup switch whereby theswitch sets up a complicated circuit and then a circuit breaker switches the power. All testingis done under electrical load.
2. Test under an application oriented specification–something that simulates actual operat-ing conditions such as environment, overloads, surges, etc. UL1054 on SPECIAL USESWITCHES and CSA C22.2 on INDUSTRIAL CONTROL EQUIPMENT for use in Ordinary(non-hazardous) Locations are probably the best specifications in widespread use. TheSeries 21, 24, 25, 28 and 31 are UL recognized and CSA certified to these specifications.
3. Test at different ratings until destruction to determine ultimate life (destruction could bemechanical failure, shorting out, dielectric failure, excessive heat rise, etc.). The test condi-tions are outlined on the SELECTOR CHART for each type of switch. The results are summa-rized below:
Both UL and CSA testing consists of two parts:
1. Product testing to the specifications.
2. Follow-up service by UL and CSA personnel at the factory, including inspection and test-ing to insure that the quality and reliability is maintained.
If all conditions are met, the switches are considered “certified electrical equipment” byCSA and “recognized components” by UL and the applications are subject to review bythese agencies to assure suitability.

UL and CSA Ratings
These recognized or certified ratings are not necessarily the limits of switch capacity. Theyrepresent the acceptable tested ratings to comply with individual standards.
Tests include:
1. Overload – 50 cycles of operation.UL – 0-10A at 150% rating ... over 10A at 125% rating CSA – 150% rating
2. Endurance–6000 operations (DC resistive; AC at .75 to .80 pf)
3. Temperature rise of contacts 30˚max. at maximum continuous current rating
4. Dielectric Voltage Withstand UL-220VRMS
5. Spacings (between live parts or live parts to ground) UL– 0-250V (3⁄65 in. min.) 251-600V (1⁄8 in. min.)
