[Oletrucks] Brake Light Switch question

[mks]

I am wanting to add a second switch that turns the power off when I hit the
brake pedal.  It would be very easy to add a second lever switch like the one
already on my 57 Chevy pickup.  My question is whether there is a lever switch
that is hot when the brake pedel is not active, and cuts the power when the
pedal is depressed?  I thought a long time ago I saw a Reverse lever switch,
but maybe that was just wishful thinking.  If anyone knows of one, please let
me know.  I am using the stock brake pedal.

Thanks, Mike
