Security caps prevent any inadvertent lever operation. When the cap is raised, the lever can be operated freely. When the cap is fully depressed, the lever is reset/locked in a stable position. They are designed for use on switches with Ø 11,9 (.468) or Ø 12 (.472) threaded bushing and lever length 17,5 (.688) outside bushing.

Note : For correct switch operation, the security cap should be adjusted properly by means of 2 nuts.
