Hello...
I need to set up a relay circuit of sorts...game show style.
If I have two push button switches, I need to set up the circuit so that the one that is activated first, lights a bulb assigned to that switch, and cancels the second from completing the circuit to light the bulb on that circuit. Does that make sense? I can kind of see it in my head but it's been a long time since I did anything like this and could use a little help brainstorming.
Thanks.

You can make a bistable with a pair of 4001 gates or 4011 gates. You will then need a couple of transistors to supply the relay current or to switch the load directly.
