I'm not sure if here is the right place to post this question but since I'm a beginner this seems like right forum group.
My wife constantly forgets to switch off the bathroom light, it drives me crazy
So I'd like to make/buy a timer that will switch the light off automatically after 2 minutes (or adjustable amount of minutes).
I assume that in this scenario I'll have to put a push button switch.
Any ideas on how to make this (or where to buy it)?
Thanks
