Limit Switches

Limit switches are one of the most common presence sensing devices used in industrial controls. Activated when an object makes physical contact with the actuator, they provide an electric or pneumatic signal. Choose limit switch type based on environmental factors and available space, then choose actuator style based on the mechanical setup of the application.
