IDEM Tongue (Key) Interlock Safety Switches

22mm Mounting Dimension Safety Switches
(Tongue Interlock)

• IDIS-1 Series - 31.5mm wide, plastic body and head<

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. They 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• When the actuator is withdrawn, the safety contacts are positively opened and the machine circuit is broken.
