AR22/DR22 Series – Fuji Electric

By adopting the release arm system, ingenious super-effortless mounting is implemented, with consideration of work efficiency.

The AR22 now uses a release arm with a wedge mechanism developed by FujiElectric FA. This enables you to mount or remove the operator and contact block without using any tools. When fitting the switch to a panel, you can ignore the panel thickness. You have only to secure the operator with a locking nut from behind the panel without any need for adjustment.
