I have a switch I want to use in my car. It is an OEM switch but it is a momentary switch. I want to use the switch to turn fog lights on and off. I know I could get a switch that latches on and off at Radio Shack but this OEM momentary switch looks a lot better.

How would I do this? Some sort of timing circuit?

I saw this on Amazon and it is in the right direction....I just don't want the output turned off 10 seconds later.

I got the idea here :
[Mk4 Golf] Modifications for the 2.0 8V - Engine, Tuning and Performance - uk-mkivs ... in the picture he describes a timing circuit.

You want it to stay on for a finite amount of time, then turn itself off? Will a Delay on Break Relay do what you want?

I don't know of any mechanical device. But you could build one using TTL. A 12 V quad NAND would work. Output of the 4011 to a NPN transistor. Transistor to a diode protected relay. Relay to fog lights.
