I had the contact slider pull away, just a little bend and it was back on track. I also saw one whos contact was rotted off, probably empty for decades with moisture ingress. Could you solder than one back together?
Yea, I have fixed a few but once the contact wire starts going I don't bother.
I have seen some with the contact arm completely worn through before the wire wore through.
They used to have a copper button on the arm, but now that part of the arm is copper and a lot thinner with no button.
Won't be long now before everything we buy only lasts 90 days, and that only if it works at all when we put in on.:D
