Tongue Interlock Safety Switches

Our tongue-operated Interlock Safety Switches with tamper-resistant interlocking resist external tampering effectively. They provide robust position interlock detection for moving guards.

These tongue interlock switches feature industry-standard housings and fit the leading edge of sliding, hinged, or lift-off guards. Additionally, with dual entry slots and rotatable heads, which move only when the cover screws are released, these switches offer various actuator entry options based on the chosen switch.

Depending on the risk assessment for the application, you can use them independently to provide positively operated contacts to IEC60947-5-1. Alternatively, you can combine them with any dual-channel safety monitoring relays.

These safety switches come in three different materials: high-specification red polyester, painted die-cast metal, and stainless steel 316. All are designed to withstand harsh industrial environments.

For washdown environments like food processing, pharmaceutical, and petro-chemical industries, the stainless steel 316 range offers protection up to IP69K. This makes them suitable for high-pressure chemical cleaning or CIP/SIP applications. Moreover, the IP69K enclosure protection, maintained by a double seal lid gasket, withstands high-pressure hosing with detergent up to +80°C and 100 psi.

Our Tongue Interlock Safety Switches suit a wide range of industrial applications, including but not limited to:

  • Automated production lines
  • Packaging machinery
  • Robotic cells
  • Conveyor systems
  • Injection molding machines
  • Food and beverage processing equipment
