Technically they work, but no, as others have said, the tolerance is terrible. If the electronics on the test bench are available, I can easily open the circuit with a magnet, but finding a place in the application to get a reliable open circuit is very difficult. Make these particular unusable. I'm not sure if this is due to the bias magnet being too strong or if the supplied magnet is made more magnetized by using other magnets to open the circuit. I believe that will happen later. Because after a few days in the open position, with a stronger magnet holding the circuit open, it seems to fail even though the device I'm using it with hasn't been touched. Since it's so irregular, I can't use it.
