These heads have roller-lever actuators that move in a circular motion until they reach a preset point and then push down on the spring-loaded actuator that opens or closes the circuit. Roller-arm levers adjust to different lengths and their rollers provide smooth contact with moving objects to reduce friction.

These heads have rod-lever actuators that move in a circular motion until they reach a preset destination or end-of-travel point, then open or close their circuit. Rod-lever actuators adjust to different lengths, actuate with little force, and handle heavy loads or forces.

These heads require lever actuators to complete the limit switch head assembly. Actuators must be purchased separately.

Plunger heads have spring-loaded actuators that depress to open and close circuits. These heads actuate from vertical and horizontal moving objects.

Roller plunger heads have wheels that spin when they come in contact with moving objects until they reach a preset destination or end-of-travel point, then push down a spring-loaded actuator that opens or closes its circuit.

These roller plunger heads and lever arms extend the roller wheel away from the limit switch body to reach longer distances than standard roller plunger heads. Roller plunger heads spin when they contact moving objects until they reach a preset destination or end-of-travel point, then push down a spring-loaded actuator that opens or closes the circuit.

These omnidirectional heads have wobble stick actuators that move in multiple directions to detect precise, omnidirectional movement.

These wobble stick heads require wobble stick actuators to complete limit switch head assemblies. Wobble-stick actuators move in multiple directions to detect precise, omnidirectional movement, and they must be purchased separately.
