Roller Lever Arm Momentary Limit Switch ME8104 1NC 1NO 2PCS

Good quality switch. I use it to trigger a light when you open a door. The roller arm is adjustable, and the device works well.

Seems to have all the features and quality I seek.

Better quality then expected. They work great, but I am using them outside and freezing rain froze the lever. All I had to do is trip manually, all ok

works great to make a sliding closet door light switch, it interrupts the 12V line on a LED string light which is easy to wire in a closet without power.

They limit the travel of my dumb waiter up and down to the storage area in my cabinet shop

They worked great, I put them on my pantry doors to automatically turn on lights when doors are open

Integrated as limit switch into remotely operated observatory roof opener system. Easy integration; no functional problems.

Hope they stand up to some environmental exposure. Using for safety limit switches on mower.Seem to be similar designs for slightly cheaper though (3 for $10 instead of 2).
