    Anyone know where I can find a brake switch like this in a "Normally closed" position?

    I've bought K&S #12-0001 and found this type to be an open circuit. This means the brake light in always on and off when pulled.

    I need the switch to be off and then on when spring is pulled.

    Art, I can check the one in the "box" if you want but most brake light switches I've ever been around are N.O. (normally open). How is it wired? I would assume power is ran through switch then lamp is self grounding, chassis ground, switching from NO to closed position would complete lamps circuit. Another option would be power to lamp and then switch-NO would then close completing ground. I wire circuits that way if power source is closer to load than switch. Scott

    Please check your box.
    When hooked to the front brembo micro brake switch it works fine but not this switch. The wiring is a harness from Trick Dual Sport.

    Art, checked the switch this am and it is N.O. (normally open) The front brake switch should just be a N.O pressure switch. Were is the power source? does power run (to) through the switch? to complete the circuit or does the switch just complete the common (ground)? With having dual switches, front and rear brakes, I would wire it so the lamp had power then complete the ground at either of the switches so when a brake is used no matter which one the lamp comes on. Check the power source and see what the circuit is. If the power runs through the switches you have to have power to each switch in parallel, not in series otherwise you have a open circuit unless both switches are in closed position. An example would be a dome lamp in a car, the lamp has power to it at all times and when a door is opened the door switch just completes the ground to turn lamp on. This way any door that is opened will turn lamp on. Hope this helps, Scott

    Scott- the power is through a switch.

    Thanks for the explanation. I think I'll just use the front switch as I really can't find a suitable place to mount the rear switch.

    I just hope the Dept of Motor Vehicles doesn't notice that I'll be using the front only - they are not the sharpest tool in the shed, ya know!

    If they do just tell them some story about how rear brakes give off more emissions and your trying to save the planet.

    lol.
    I'll just squeeze the front brake as I tap the rear brake lever- they'll never know.

    DMV- are dull tools

    Yeah Art the DMV guys aren't too bright, i once took a Kawi to inspection with a Yamaha gas tank on it , with the Yamaha on
    the side written in huge letters & they didn't even notice :excuseme:.

    I was half expecting a search of the motor numbers etc, or at very least someone saying it this the right bike for this reg, but they didn't
    even say a word, cueless :doh:.
