Rear Brake light switch question
On the universal unit it is the spring that absorbs and contains this movement.
I apologize for the confused question, hope I explained myself well. Thanks in advance.

Re: Rear Brake light switch question
At rest the "switch" is engaged/pressed by the bracket, and then upon pressing the foot brake the switch is released. The two parts are not connected - they only touch each other. See photo.
Hope that helps,

Re: Rear Brake light switch question
So this switch is pressed to Normally Closed position, and as soon the leaf of the rod is not pressing it anymore, the contacts are opened to N.O. for the current to flow?

Re: Rear Brake light switch question
So, as I understood it - the plunger inside that switch is always pressed by the small angled lever mounted to the rod, thus preventing current to flow and activating the brake light (hence a Normally Open device) - until the brake is engaged; then the rod with that angled lever on it is moving forward, releasing the spring loaded plunger so the switch is now closing the circuit, allowing current to enlighten the rear brake light.
Am I right here?
Just want to be sure, as all the switches I know in that area on other bikes are Normally Closed items and function the other way around, so this is unique.

Re: Rear Brake light switch question
All other brakelight switches are usually normally open en you have to pull on the plunger to close the contacts.
