Potter Amseco ODC-59A Overhead Door Switch

Put them on my garage doors to shut heater off when open. Worked great

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.

This thing wired up in a few seconds and provided a much more reliable easy to mount solution for my garage door sensor. I had a cheap plastic white sensor wired up first and it was a pain to get to reliably recognize and would also keep shifting and getting dislodged. This thing comes with a serious bracket and plenty of ways to confidently mount. Plus the most important part, it has a very generous tolerance on the sensor, so placement is nowhere near as precise as the little cheap plastic magnetic sensors you can get in bulk

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

they are exactly what I was looking for ,with the fair price

Long Lasting Construction

fast delivery good product

It is not specified. But, I would have expected this switch to be normally closed, such that it is closed when not activated by the magnet. Its not! It works in the opposite mode, such that it closes when activated by the magnet.

Works great

This exactly what I needed to replace a broken one without calling the alarm company for service.
