How do I make a 12 volt, touch sensitive momentary switch to start a car? Answered
I would like to create a touch sensitive panel that will allow me, through contact, to activate the starter on a car.
From what I have read on Instructables in the past, there are several ways to make 120v swtiches like this through the use of metal objects. These have all been On-Off switches for things like lights or sound. I would like to create a momentary switch that activates by touch in a 12v system. If it is possible to do through a metallic contact point that already exists (part of the dash, or a trim bezel for example) that would be ideal. All I really need is some kind of activation mechanism that transfers enough current to flip a relay when I touch it and that will stop when I remove my hand.
Anyone have any ideas?
