TImer switch sicks

I think the reason my (spring wound) bath fan timer switch sticks is when I reset it, ie, change it form say 20 min to 40 min. It is spring wound. I know folks who have such switches for twenty years, and they blame me for my problems. I have a replacement, and I changed it before every three years, but am curious if it's my fault to figure it out. Also, may have to extend the wires using scotchlock, so reluctant.

Sorry, but your post doesn't make any sense.

If it is a mechanical timer, when you set the time, it starts a clockworks mechanism that closes contacts for the length of time set, and then opens t he contacts, to shut of the bathroom fan, for example. If it is a purely e lectrical type of timer, a motorized clock does the timing for opening a se t of contacts and shutting off the ventilating fan.

THanks. I seem to be able to avoid the problem by not interrupring the cycle. If I reset the spring timer from 20 min to 40 min it gets stuck at 40 min. If I let it finish then reset it, it seems not to stick (as much?)

I've been replacing the switch when it get stuck, every thre years or so, except a friend with an entire building full of them (running two decades) tells me to timer isn't the problem, I am.
