install a regular switch or a timer after the breaker.

not only more convenient, but long term using a breaker as a switch can lead
to breaker failure.

The first "test" I did was to replace the breaker -- with one that has seen
*no* use.

So, while flipping the breaker on and off a few dozen times a year *may*
fatigue the mechanism, it's not the cause of our current problem (unless
the replacement breaker happens to be defective from the factory).
