Potter Amseco ODC-59A Overhead Door Switch

Excellent product, well made, worked great. I used it with a raspberry pi to make a MQTT garage door opener for home assistant.

This has worked flawlessly in my Wemo Maker garage door setup.

Had to replace one of these after 16 years, was happy to find this as a direct replacement. Apparently these switches can get stuck in the closed position if they are installed on a garage door that is seldom opened, which is what happened to the original one. I have another that is still working fine after 16 years (on the garage door that is opened and closed daily).

Long Lasting Construction

This switch is Normally Open, BUT Closed WHEN in vicinity of the magnet. I use it on my garage door to operate a security system feedback circuit. It is provided with about 2.5 ft of flexible metal conduit so that the wire can not easily be cut with a knife when the door is shut.

Works fine

Easy to install and use with PLC system using 24 volt DC to monitor some gates and doors. I hope they have a version with longer wires. If you know what are you doing you can use this with any industrial automation and home security automation or IOT system with no issues whatsoever.

Great replacement, the holes were closer than the Honeywell switch it replaced, so I had to drill new hole in concrete.

Its a simple reed switch, but appears solidly constructed. I have this hooked up to a Fortrezz MimoLite to sense when the garage is opened/closed. Control via HomeSeer.

I wasnt sure quite what to expect from this as a DIY project, but these worked out great. Theyre designed to be mounted on the floor, but after some testing with a multimeter, I determined that the orientation of the magnet to the sensor isnt all that important. As long as the magnet is within about 2 inches of the switch, the switch closes and I read a short on the lead wires. I went ahead and took the magnet off the steel angle-bracket it shipped with and just mounted the magnet directly to the top of my garage door. Then I wired the sensor side to the garage wall next to the magnet. With that wired into my security system, everything is now up and running and Im a happy camper! I cant think of anything bad to say about these. They did what I wanted them to do right out of the box.
