• Always lockout and tagout the machine prior to installation
The Touchswitch™ is an electronic limit switch. When a belt misaligns or a pulley moves over and
contacts the sensor, the built in solid-state electronic circuitry detects the lateral force of the belt or pulley
and activates a voltage free relay contact. This relay contact is used to immediately alarm and shutdown
the machine. The face of the sensor is made from hardened stainless steel, so that there is virtually no
wear when a belt contacts it. The sensor is not affected by dust or material build up and will still work
when completely covered by material. Sensors are normally installed in pairs on opposite sides of the
machine. Usually a pair of sensors at each pulley is used, but additional pairs can be installed as required.
An external test knob allows for quick and simple sensor / system testing.
