Tongue (Key) Interlock Safety Switches

Tongue operated Safety Interlock Switches are designed to fit to the leading edge of sliding, hinged or lift-off machine guards to provide positively operated switching contacts and provide a tamper resistant actuator mechanism.

• 16.5 mm - 18mm mounting profile (Inch-X)
• 16.5 mm - 22mm mounting profile (MK-1)
• M16, 1/2" NPT threaded opening or M12 quick disconnect connection
• 90 degree adjustable head
• Standard and compact housings
• Force guided NC contacts
• Rotating heads with dual actuator entry
• Purchase actuating key separately (See accessories)

Tongue operated safety interlock switches are designed to provide robust position interlock detection for moving guards.

• The switch is rigidly mounted to the frame of the guard or machine.
• The actuator is fitted to the moving part (frame) of the guard and is aligned to the switch entry aperture.
• The actuator profile is designed to match a cam mechanism within the switch head and provides a positively operated, not easily defeatable, interlock switch.
• When the actuator is inserted into the switch, the safety contacts close and allow the machine start circuit to be enabled.
• When the actuator is withdrawn, the safety contacts are positively opened and the machine circuit is broken.
