What Is An Electromechanical Limit Switch?

In the broadest sense, a limit switch is an electromechanical device designed to detect the presence or absence of another physical object, usually a piece of machinery that moves or travels. Perhaps one of the best ways to understand limit switches at a high level is through the many applications they have in the real world.

  1. Detect when a car or garage door is open or closed.
  2. Detect when a door to a vehicle is not fully closed


Safety Interlock Switches – Limit Switch Design Considerations.

One of the most common applications for our high performance Limit Switches is in the area of safety or performance controls for extreme duty machines. These are applications where failure of some component or system would be catastrophic or costly to replace. An example of this would be the safety interlock limit switches found in heavy duty machines in the industrial vehicular space (a forklift), or construction equipment (backhoe loader etc…) and aerospace fail-safe
