Limit Switches

Limit Switches — New & Used

Limit switches are precision electromechanical devices designed to detect position, movement, or presence within industrial systems. They provide mechanical actuation feedback for safety interlocks, machine control, and automated motion systems. Available in plunger, roller lever, hinge lever, and rotary styles, limit switches are essential for ensuring accuracy, safety, and repeatability in automated equipment.
