Trapped Key Interlocks

The trapped key system works on the principle of releasing heavy duty coded mechanical keys in a pre-determined sequence to ensure machine power has been isolated before any access can be made into areas where hazards or dangerous machinery is present.

  • All available in die cast or stainless steel
  • Up to 48 standard key codes available
  • Other custom key codes available on request
  • Sequential or non-sequential release
