Approvals
Designed and manufactured in the UK the KM Tongue Interlock Safety Switch has been designed to provide position interlock detection for medium to heavy duty moving guards.
They have particularly robust die-cast housings and are designed to fit to the leading edge of sliding, hinged or lift off machine guards.
Options of die-cast head (KM) or stainless steel 316 head (KM-SS) are offered – see Part Numbers below.
They provide a forced disconnect of the safety contacts at the withdrawal of the actuator and have an anti-tamper mechanism.
The rotatable heads have dual actuator entry positions to give up to 8 different entry positions. For increased extra durability, flexible actuators and stainless steel head versions are available.
Contact blocks are replaceable with optional explosion proof versions.
High holding force versions are also available for applications where vibration can be a nuisance.
