BaomainLimit Switch BM-3104 (TZ-3104) Roller Lever Plunger Momentary SPDT NO+NC IP67 Waterproof

Works great so far, used this for a clutch switch for 2-step activation

If the solar array over runs the magnetic stops this is a safety backup to keep from breaking the drive motors and chains. Sturdy design and low cost backup that has already saved us money. Will be getting another as a alarm trigger on my own garage door. I've used similar repairing car wash gantry stops for more money so for great function and affordability this is now my go to.

These are sealed. Handles Chicago weather. Only thing is the lille bearing on the arm not as much. Still working, but starting to go.But four wires - easy. Normally open or closed (or I guess both...).I've replaced ALL the other brands with this.

Used switch to replace a limit switch on a beach Butler elevator. The previous switch had been penetrated by water and rusted. Since this one is submersible I chose it. The switch was the perfect replacement.

had to order new 2 times and had to cancel because orders wouldn’t ship after 2 days with prime, ordered 3rd tome for “used” and finally received product after a week, but product is robust and strong do do heavy duty work

Bought this limit switch to wire up a caution signal as a lower z-axis limit on my milling machine. Wired it so a buzzer sounds as I reach that limit.

The media could not be loaded. Since WiFi is unreliable in my unattached garage and I can’t see the door from my house I use this switch to turn on an outdoor light when the door is up and I can see it from my kitchen window!

The switch doesn't have a very clear electrical on/off signal. I wasn't able to use them for what I needed.
