Here is a real simple one, Guys. My son was asking how we could keep the light on using a push button since it is momentary. I have seen the latch over and over again in ladder logic and relay logic, but I had to figure out how to make it work here. Anyway, the N.O. push button is the start button, which turns on the relay and latches the circuit on. Pressing the N.C. push button opens the circuit and releases the latch.
