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
