ME-91011NC+1NO Flexible Coil Spring Rod Momentary Limit Switch 2pcs

After leaving the garage door on our heated garage open for 3 hours at -10 degrees F, I decided I needed a safety. I chose this design as it had a spring contact, so I did not need to be quite as precise in location. Wired NC mode in series with the thermostat it keeps the heater from starting up if the garage door is open. They seem very well made, and have very easy access for wiring.

These limit switches are well made and work as expected. The description and the product photos are accurate and well done.In my application, I used these switches to monitor a garage door position and trigger warning lights while the door is in motion. The limit switches have worked flawlessly since I installed them many months ago.

I used them on an automatic horse feeder I built. They have been functioning fine in temperatures down to -1 degrees so far.

Easy to install

I used one to light a light above the house door to the garage to tell me when the door was open and closed. I got tired of my neighbors knocking on my front door at midnight to tell me the door was open.

It is very easy to connect/install and operate.

These are fine for use at "end of travel" applications. Don't use it in applications where the carriage triggers and runs past the wobble spring actuator because the fly-back destroys the switch. Light duty- can't beat the price.
