Miniature Tongue Interlock Safety Switches (Stainless Steel)

Our miniature tongue operated interlock switches feature a tamper-resistant interlocking mechanism which cannot be easily defeated. They are designed to provide position interlock detection for small moving guards.

These switches feature a compact design (30mm wide / 22mm fixing) and can be fitted to the leading edge of sliding, hinged, or lift-off guards. With dual entry slots and rotatable heads, movable only by releasing the cover screws, these switches offer eight different options for actuator entry.

Depending upon the risk assessment for the application, they can be used independently to provide positively operated contacts to IEC60947-5-1 or they can be used in combination with any dual channel safety monitoring relays.

They are suitable for harsh environments like Food Processing, Pharmaceutical and Petro-Chemical Industries. This is due to the Stainless Steel 316 housing, offering protection up to IP69K for use in high pressure chemical cleaning or CIP/SIP applications.
