LATCHING_SWITCH_CIRCUIT

One button turns the LED on, the other turns it off. If you apply a positive pulse to the SET input, the output tums on. It remains on until a positive pulse is applied to the RESET input to turn it off. (TTL flip-flops such as the 74LS74 are actuated by negative, rather than positive pulses.)
