I purchased the switch you show, maybe I donot understand how it is suppose to work but it got hot and started smoking, I touched the spring and burnt myself good. I have a 65 positive ground, I ran two wires from the wires connected to the spade connectors on the origional 3 way hydraulic switch (removed from the switch). If you put those two wires together you have or I have brake lights. I ran those wires to this little switch which I mounted on the pedal box and attached the spring to the back side of the brake pedal. When you push on the pedal that pulls the plunger out of the switch and you should have brake lights, according to my thoughts. Where did I go wrong, no lights and severly burnt fingers????? Is the car grounding it out?Why would the switch care?
