GE In-Wall Mechanical Countdown Timer Switch, Spring Wound, Up to 15 Minutes, 1-Minute Intervals, No Neutral Wire Needed, Ideal for Lights, Exhaust Fans, Heaters, LED, 15303

I bought it for my bathroom exhaust fan and wanted a 15 minute maximum time limit. The black knob is twice the size of my past timer. The timer easily turns and works well. You can hear the ticking and I know it is working. I was glad it worked with just two wires for Line 1 and Load 1 slots. I was disappointed that my two other dimmer switches also were working on just two wires.

I got this to use in a 12-volt DC application even though it's designed for a 120 volt AC application. It seems to work great and I coupled it with an outdoor cover so it can turn on the pump for the sink on the exterior of my camper. And this way I never leave the pump on.

Very solid and commercial feel.

Tight fit in my box. Works as advertised, but I expected 1 hour instead of 15 minutes, but that's my reading failure.

Used in an application where the light switch also operated an electric space heater. Solved a problem of forgetful users.

Works great. Installed in my smoking room to run a ventilation fan that will shut off after a short time after I leave. It does the job and without any problems for over a year.

Well its just what if says. A mechanical timer. I have to manually set it so the earth does not stop.Good thing to because if the planet stops spinning bad things would happen. So i use this timer to keep everything in place and the world spinning.I have purchased before snd the advantage of a mechanical timer is you don’t need electricity. It was not expensive for my application and it does make a soft ticking noise if the place is quit. Its actually quite soothing. You do need to turn it on at least a quarter of the way if you only need it on for a short time. But if you are using to keep the planet in check please turn it all the way. So the people in middle earth don't get upset snd come up and bite us!!!

The timer function stopped working within a week of installation. The switch still works, but the timer doesn’t shutoff the power after the set amount of time…which is the entire purpose of the timer switch.
