Typical Applications
Operator control panels for industrial machines.
Mode selectors (e.g., Auto/Manual/Off) in automation systems.
Pilot devices in manufacturing control cabinets.
Multi‑position control interfaces where a maintained selection is required.
The ABB C3SS1‑30B‑02 is a compact, non‑illuminated rotary selector switch designed for industrial control panels and automation equipment. It features a 3‑position maintained mechanism with a short handle, allowing an operator to select between three fixed positions (commonly labeled A, B, C). The switch housing and parts are built for reliability and robust performance in a variety of environments.
