Anyone find a source for the motor cutout micro switch imbedded in a Magura brake handle? It's a replaceable part, but I have yet to find one. I can usually clean the buildup of road debris from the mechanism but I have two with bad contacts inside the sealed switch. So far, I've only been able to find the complete lever assembly and the $65 price tag is a big turnoff.

If I have to, I'll convert to the hyd. pressure switches used on newer brake systems:

A bit cheaper but a lot more work than just replacing a switch.

Are the Magura mineral oil?
If so I wonder if you can use a Tektro lever... the brake sensors are easily found/replaced

Yes, Magura uses "Royal Blood" mineral oil.
I'll look into the Tektro, but I doubt the parts are compatible.
Thanks for the tip though.

Yeah I don't know how you can know other than testing as those types of specs are not published. You might have a different line fitting but that's easily changed. More important is the operating pressure/fluid travel amount with a lever squeeze.
That said... How different can it be??
 
Curiosity got me and after doing a little reading consensus is that my suggestion isn't as plausible as I thought....basically for the reasons I stated.
That said I couldn't find any results from anyone that actually tried it. So maybe if I had the hardware lying around I might try it but I wouldn't spend any money to.
You find any source for the sensor itself? Does Magura have any helpful customer service?
 
The switch wasn't the only problem. It turned out to be a much more expensive repair. After I disassembled the brake handle, I found the hydraulic reservoir had a fine crack that was slowly leaking oil. It was the reason I had to keep bleeding the system to restore good braking action. I had to replace the entire handlebar assembly. The replacement part came with a new handle and switch, so problem solved.
