    I bought this switch, hoping I could rig it up to work for my neon cathode in my computer. The neon cathode has a red and a black wire coming out of the transformer for a switch. The push button switch has a red, black, and white wire coming out of it. It says the white wire is for a relay in a 12v system, but is there anyway I can wire it up to the cathode anyway? (I suck at electronics, so complex diagrams and stuff are useless :naughty: )

    My main question is, can you straight wire it without any transformers or relays or anything? A push button cathode would be awesome :rock:

    You can, but then you would have to hold the button in to make the cathode stay on...

    a d-flip-flop thould be noce for what you need.. pretty easy to wire up aswell.. :)

    A Flip-Flop you say?:

    Replace the wore FAN with COLD CATHODE CIRCUIT and that should work.

    :duh: damn must have forgotten abotu that when i put this diagram together, TIP's are pretty tough but it would b a very good idea yes.

    What other transistors would work as well? Any NPN?

    Any NPN that will carry the relay coil current. A 2N2222 (600mA) should drive 99% of relays, 2N3904 will drive small ones up to 200mA.

    I'd also add a 470R base resistor to limit current drawn from the flip-flop, and you need to ground inputs on the other half of the 4013.

    With no switch debounce components you'll get a few false triggers. :sigh:
