U87 pad switch permanently 'on'

<< < (2/2)

I have seen the opposite problem a few times now where the reed relay will not close.
Holding a magnet near the relay would actuate it. I ended up paying quite a bit of $$ to Sennheiser and
replaced the whole switch assembly.

Exact distance between reed switch and circuit board is crucial for switch operation.
You can adjust the distance by inserting a feeler gauge between switch and circuitboard, as you solder the switch in place.
