Potter Amseco ODC-59A Overhead Door Switch

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

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

This switch stands out above all the others. Ive played with dozens of these and this one has the best connection which was imperative for my gate which bounced and never quite line up smoothly.

Ive had these installed on my garage door for several months and they work great.

Very nice contact. Rounded top and side. Armored cable long enough to reach behind the garage door railing. The magnet is also nice since you can adjust it to you likings. It was perfect fit as a replacement.

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.

Works well, probably best option for the money. I was unable to mount this on the side near the steel track, there was too much interference with the magnet to activate the switch. I opted to mount to the top of the garage which was not perfect because the top of my garage panel is not flat. Overall, very pleased with the result. The product itself is very well built.

Works great. Seems to be very durable.

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.

Received it on time. Installed it quickly. It worked like a charm. What more could you ask for? I would definitely buy it again. It was very reasonably priced as well.
