Overview

The Fuji Electric AR30JR-2B20B is a two-position maintained key selector switch designed for industrial control panel applications. It uses a standard 30mm panel cutout and features a Key Type B mechanism that can be removed in both the left and right positions. This dual-removal capability gives operators the flexibility to lock the switch in either state, helping prevent accidental or unauthorized operation in environments where equipment safety and access control are priorities.

Equipped with two normally open (2NO) auxiliary contacts, the switch can drive two independent circuits when actuated. The maintained action means the switch stays in its selected position once turned, eliminating the need for continuous operator input. Built by Fuji Electric, a manufacturer with a long track record in industrial electrical components, this key switch is a practical choice for machine control, safety interlock, and mode selection applications where reliable, secure switching is required.
