Description

Limit switches work great on anything from end stops on CNC machines to impact detectors on small roaming robots. They work like any other momentary switch and provide both the normally open and normally closed contacts. Limit switches differ in how the switch is actuated – limit switches typically have a metal lever on them. The metal lever acts like a spring and protects the physical switch from repeated impacts.

This specific version has a small roller wheel on the end of the lever, making for less drag on objects moving past and triggering the switch. Connections are 4.7mm / 0.187″ Quick Connectors, and as with most switches of this type, both the Normally Open and Normally Closed circuits are available. Mounting holes are found at a fairly standard spacing for switches of this size.
