Using two of these to detect when my air line drops to 45, and then another for 20PSI - for pneumatic railroad equipment. These work great, very sensitive. Normally-closed Inputs are being fed into a PLC which debounces some of the flutter that occurs when they get close to the setpoints. For the price, these are perfect.

I’m using it as an NO switch to control the vacuum for my sand blasting cabinet so I don’t have to listen to it unless I’m actually applying pressure. Awesome little switch.

Some reviews complain about the lack of hysteresis, but that’s not what this device does. There are other types of sensors that have on pressures and off pressures, but this one just has a single setting - and it is adjustable! This is just what I needed. The other types are good for turning on and off the compressor itself, but this one just lets me know when a specific pressure is hit. It also has both normally open and normally closed connections. I’ve just started using it but so far is working great.

Does what the description says. Used mine to power indicator lights on my welding gas tanks so i don’t accidentally leave the valves open when not in use. The normally open and normally closed contacts allowed me to power up a red light when the tanks are closed and a green light when the valves are opened. Nice little switch for a decent price.

I was able to adjust the pressure down to 75 psi. It was not hard to use

It didn't even make it a week when both sensors failed.During this cascading failure the system produced a huge amount of pressure which exploded the back of the switches out.These are not safety switches.These are not safe at all.These switches are dangerous
