I fixed the front brake tail light switch! Seems that the whole switch is very much a Rube Goldberg fulcrum-type device, using spring tension contained by some cleverly designed bits of plastic and metal. It took me a few tries to get the combination right, so that the plastic push rod was actually being pushed upon by the spring mechanism. The key is to get the two round contacts within range of each other so when you use the brake lever the push rod is released, causing the mechanism to snap the two contacts together, completing the electrical circuit.
The idea here is the switch, when it is static, is in the completed circuit mode - always a complete circuit. Interesting, the switch is only in this static state when the front brake lever is used, moving the front brake's metal tab away from the pushrod, allowing the springy thing to push Simple, but very cleverly conceived, I must say...........(there's so many small moving parts on these machines, it's a wonder they work at all for very long!?!)
A bit of crazy glue buttoned up the two halves together, since I had to break the plastic 'one time only' deals that hold the two housing pieces together. If you ever do this repair, make sure you're careful with the crazy glue, and actuate the push rod so any crazy glue leakage doesn't make any mayhem for the moving bits.
Shows the switch re-assembled, but i've not yet plopped in the black push rod....
Push rod in place.......
Two halves glued and clamped! (Saved $30 on a new switch, and probably saved my ass in the future!
