ABB C2SS1-10B-20 Safety Relay Module

ABB C2SS1-10B-20 is a compact 22 mm panel-mount selector switch from ABB’s pilot-device family, finished in black with a short actuator. It is a two-position, maintained selector (SPDT: single-pole, double-throw) intended for manual mode selection and signaling in industrial control panels. The device fits standard 22 mm cutouts and is documented in ABB’s pilot-device catalog alongside other C2SS1 variants, making it a common choice for machine control where a reliable operator input is required. The exact variant is identified by the C2SS1-10B-20 part number, ensuring the correct actuator style, contact configuration, and mounting method for panel installations in automation and safety-related control schemes.
