OudtinxMagnetic Holder Bed On/Off Switch Holding Power

These magnetic switches are plenty strong enough to hold a fence down for woodworking. I was so impressed I purchased a second one. Another company makes similar ones but want 4x the cost. Definitely happy I went with these instead.

Had bought some Magswitches for use on my table saw, but they are very expensive, so after seeing a YouTube video on making cheaper equivalents, bought some of these magnets, which turned out to be a great money-saver. These are bulky compared with the Magswitches, but that doesn't matter for my projects.

I read some reviews that said the magnet was not very strong. I attached this to a filing cabinet (0.030" metal thickness) and could easily pull it off. I attached it to a 1/8" thick plate and could not pull it off. Magnet ratings are for straight pull off. A magnet can always be "peeled off" with lesser force. I bought this to add to a articulating arm desk lamp for a work bench. The bench top is 3/8" thick steel. It held very well. Even with the maximum cantilevered load shown in the photos it held the lamp quite well. I am glad I didn't pay attention to the reviews that said it was not strong.

when you are working in confined spaces, this is the way to go: off and on.

It is strong if the pull direction is straight up only. I have equipment to measure the stated poundage but didn't take the time to do that. However if there's the slightest tipping of the magnet, it becomes very weak. Also,, the included T handle wouldn't screw into the threaded hole in the magnet. I had to go buy an M8x1.25 tap and ream it out. That annoyance but primarily the lack of power made me return it.
