G20 Micro Switch 3-Pin

 

Limit switches can be used in a variety of applications; they are versatile, from an end stop on a CNC machine to a shock sensor on a small rover. They act like a momentary switch and provide normally open and normally closed contacts.

 

Limit switches vary in how the switch is operated - limit switches usually have a metal lever on them. The metal lever acts like a spring and protects the physical switch from repeated impacts. There are two mounting holes, making it easy to connect to machinery, robots, or other projects.
