1 / 4 page 3-2 Interlock Switches Tongue Switches Elf Description The Elf is a tongue (or key) operated safety interlock switch designed to fit at the leading edge of sliding, hinged or liftoff guards. The Elf ’s unique miniature housing (only 75 × 25 × 29mm) makes it the smallest interlock currently available. It is designed for smaller machines such as printers, copiers or domestic machinery which, until now, have been unable to use safety interlocks due to space restrictions.With its dual entry slots and rotatable head, the versatile Elf can offer up to eight different actuator entry options. Operation of the switch is achieved through the insertion of a specially profiled stainless steel key that is permanently mounted to the guard door. The semi-flexible key allows the Elf to be used on small radii doors (60mm or 2.36in). The Elf is available with 2 N.C. or 1 N.O. and 1 N.C. safety contact and conduit entry (1 × M16 or connector style) sealed to IP67 (watertight and dustproof). A blanking plug is supplied for the unused key entry. Features • Ideal for small, light weight guards • The smallest interlock switch available • Contacts, 2 N.C. or 1 N.O. & 1 N.C. • Eight possible actuator entry points, easy to install • Environmental protection: IP67 Applications Note: Lift-off guards require good alignment when using tongue actuated interlock switches. IMPORTANT: It must not be possible to lift the guard without actuating the interlock. An interlock on either side may be required.
