What equipment is typically part of a limit switch to mitigate travel damage?

A limit switch is designed to control the movement of mechanisms and prevent them from moving beyond designated limits, thereby avoiding potential damage during operation. Typically, a mechanical stop is included in limit switch assemblies to physically restrict the travel of the machinery or device. By providing a solid barrier, the mechanical stop ensures that components do not exceed their designed travel distance, which could lead to mechanical failure or operational hazards.

The adjustable arm can modify the actuation point of the switch but doesn’t provide a physical barrier to prevent travel damage. An encoder serves to measure position or speed, but it does not serve the same protective function as a mechanical stop. A guide rail might assist in keeping components aligned, but it also does not prevent them from moving too far in either direction. Therefore, the inclusion of a mechanical stop is essential for ensuring safe operational limits and minimizing the risk of damage.
