I am currently working on a customized case and have a question about setting up the lighting. I purchased a Bulgin Vandal switch that I am planning on mounting into my case to switch all of the lighting in the case on and off. I have two cold cathode lights, and two led enclosures that I plan on mounting into my case. I would like to buy or make a junction box of some sort that I can connect all 4 lights to, and then connect the switch to the junction box to turn everything on and off. Any help or resources would be appreciated. Thanks.
Simplest way would be to use a debounced flip-flop circuit to latch the switch, as demonstrated at cpemma's website. Basically, the flip-flop will turn your momentary switch into a toggle switch, while the debouncing circuitry makes sure it only changes states once per press. If you can't get a hold of a MOSFET, a NPN transistor that can handle 1A should suffice. Other than that, all you'd need to do is make sure your cathodes get +12V, your LEDs get +5V (assuming they run off of +5V) and the negative leads are tied to the gate/collector of the MOSFET/transistor you use on the flip-flop's output (note: I probably got the names of the leads wrong there, but it should be easy enough to understand what I mean).
