Telebar on/off switch issue

[Electronic M]

The click is usually a mechanical detent on the control shaft rather than the switch so the switch contacts could be completely removed and the control would still click.

It's not uncommon for the contacts to stick in a position (on or off depending on design and position it was in when it stuck). And provided the contacts did on weld them selves on or the mechanism that actuates them got damaged it should be a easy fix with some lubricant.

A back up plan if it is worse than a contact sticking is to send it to a control rebuilder(there are one or two good ones in the radio collecting community that will do TV controls too).
