20Pcs Micro Switch AC 1A 125V 3Pin SPDT NO+NC Hinge Lever Momentary Push Button Micro Limit Switch for Arduino

They are switches. They switch on and off. This was exactly what I needed, plus it was an exact fit to replace one inside a battery for a dyson v7 vacuum. For some reason the on/off mechanism for these vacuums is INSIDE the battery. Thankfully, these are a near-identical replacement, just need to get creative with soldering. They are a bit delicate. I broke 2 by accident when strength testing, but you get a package of 20 so its ok

I got them for my Dog Ball Launcher! The switch that recognizes there's a ball there got all gummed up and wouldn't work properly! Completely intermittent, decided to work when it wanted to! But now it works great again! Thanks

They feel and click like the real thing.

Not alot to say, they're micro switches, not motorcycles. They work and seem to be decent build quality.

So far, so good. I was looking for a specific sized micro switch, and these fit my specs exactly. I've used around half, and so far all work perfectly.

I installed and tested almost 20 of these switches, and they all worked reliably. Considering they cost only pennies, that's pretty amazing. I needed the tiny size, and these switches fulfilled that need.

These switches are well priced and well built for slide or push contact. However the advertised NC option is unusual, for the push lever would need to be forced closed to create a "connected" condition, then released to produce an OPEN condition. I needed NO for my hobby application so they were right for me - slide to make a connection. As a bonus, there are two holes in the body which might be used for screwing the switch to a mount of some sort.

Just check double check the pinout to see which pin the the common.
