Mechanical Endstop / Limit Switch

This mechanical limit switch (micro switch) is a precision snap-action device used to detect the presence or absence of an object. It features a metal lever arm and provides both Normally Open (NO) and Normally Closed (NC) terminals. It is widely used as an endstop for 3D printer axes (X/Y/Z) to prevent over-travel, or as a collision sensor in autonomous robots. Rated for high reliability and millions of cycles.
