AD-22-22SM

AD-22-22SM

The AD-22-22SM is a 22 mm panel-mount control element commonly used in industrial and automation control panels. It integrates a push-button or indicator assembly designed for operator interaction or status indication. Compatible with standard 22 mm cut-outs, the AD-22-22SM fits modular control stations for start/stop commands, fault indication, and control logic interfacing.

This device is widely used in motor starter panels, PLC control cabinets, distribution boards, and automation consoles.
