Are switch timers prone to failure?
Several years ago I was shopping for new exterior lights when I discovered the "self-adjusting wall switch timers" My new lights could be wired to these switches, and they would then be on timers. Unfortunately after a couple of years the timer switch I had in my garage failed. The electrician blamed it on the cold in the unheated garage so I replaced it with a standard switch. Now a second switch has apparently failed and this switch is located in my house, where it never gets below 60 degrees, so cold shouldn't be a factor. So I am wondering are these types of switches prone to fail after a few years? I don't want to invest in new ones if I will just have to replace them every few years.
Thanks for any info!
