This is a single limit switch fitted with a ball plunger actuator, used to signal the position of moving guards or mechanical components within a safety automation circuit. The ball plunger design allows contact with cams or actuating surfaces from varying approach angles, making it suitable for applications where precise linear alignment cannot be guaranteed. It is typically installed on machine guards and panels where positive mechanical detection of position is required as part of the overall safety interlocking system.
