Rear brake light switch alternatives?

andyd · Jun 11, 2026

Hi guys,
Anyone replaced the std commando rear brake switch with a better alternative? After several decades of dealing with the oem switch I'm thinking time for a change!
There are a multitude of switches now out there and there must be several that can be modified to fit a commando.
Cheers.

I use a push/pull switch and spring from an old Honda dirt bike from the 70s that I had laying around, easy to install and has been on my Norton for over 30 years now.

Find a heavy duty microswitch with normally closed contacts. Rare. But you can find single pole double throw (SPDT) microswitches which work. I made up an aluminum adapter plate to bolt up to the thin slotted plate on the brake pedal to adjust as the original. I will take some pictures tomorrow morning. (I bought 10 switches at the time, cheap, from a surplus house.)

I have had the slightly older version of this on my bike for the last 10 years. All good.

I made a simple bracket so you can use any Japanese style switch instead..

To hold the modern type of rear brake light switch instead of the big (for what it is) square block thing.

BINGO !!!

toppy gets the freeby

You almost had it on your first guess.

P.M. me your address and I'll send you one asap.

So here's how it fits..

Just back off the rear adjuster a few turns until you can pull the outer cable back at the footrest bracket far enough to hook over the cliff_hanger (ideally with the switch already fitted, maybe half way down it's thread), *** Important*** make sure the reduced section of the ferrule will pass through the hanger...
