Bump Switch

I built one out of an old door bell switch back yrs ago , worked ok .
the first car i had had a busted ignition switch

at first i just jammed a screwdriver in there and used that to start the car
but back then, i would get pulled over for speeding alot and the cops never took too kindly to my screwdriver key
so i ended up rewiring it and using a door bell switch as a push button starter
