    Logic relay switch

    OK, so Ive got these great illuminated buttons (see here) which are "push to make". What I want is a schematic of a circuit that I can connect to a relay so when I press the button once, the relay switches on and stays on; when i press again the relay switches off and stays off until I press again to turn on. Does anyone have any ideas on a circuit that can do this simply?

    try this. i just built it. i got it from mpja.com. it is a new kit for them -only in their catalog when i got it-not on the web page. you can call them. jumpers allow you to have relays "latch" on/off or momentary.
