[Robotgroup] The Magical, imaginary switch

[Paul Atkinson]

It also sounds a lot like a relay, with a latching relay being the "pulse it
to turn on and pulse it to turn off" variety.

I think you can find a 7-9V relay at Radio Shack that *might* work at 6V.
The contacts can handle 12V at some reasonable current. They also have a 5V
1A relays that might work with a diode drop. Both are under $5 each.
