Latch CircuitNOR gate bistable
Notice that you must have a switch/resistor voltage divider at the inputs to the NOR gates. With a NOR gate latch, the inputs are held LOW and pulsed HIGH. This means that you need pull-down resistors. Compare this circuit with a SET/RESET latch bistable built using NAND gates.
