Elf Miniature Tongue Interlock Switches

Our Elf™ Miniature Tongue Interlock Switches are tongue-or key-operated safety interlock switches that fit at the leading edge of sliding, hinged, or lift-off guards. The unique miniature housing makes the Elf interlock switch one of the smallest of its kind currently available. This switch is ideal for smaller machines such as printers, copiers and domestic machinery which, until now, have been unable to use safety interlocks due to space restrictions.
