Overview

The ABB M2SS1-31C (SKU: M2SS1-31C) is a 2-position maintained modular selector switch from ABB's Electrification division, designed for precise state selection in industrial control panels, machinery, and automation systems. This illuminated selector switch features a short handle, a clear bezel, and a premium chrome metal finish, ensuring durability and corrosion resistance in harsh environments. The Ø 29 mm (1.14 in) bezel diameter and 48.5 mm (1.91 in) total height make it compatible with standard panel cutouts, while the 43 mm (1.69 in) body height and 26.5 mm (1.04 in) depth behind the panel provide a compact footprint for space-constrained installations. The M2SS1-31C operates on a 2-position maintained principle, meaning the selected position remains engaged until manually changed, providing reliable state indication for critical control applications. Its illuminated feature delivers immediate visual feedback on the switch's status, enhancing operational safety and efficiency in process automation, building management systems, and machine control systems. The chrome metal bezel type and clear color ensure a professional aesthetic while maintaining resistance to environmental contaminants. This selector switch is part of ABB's modular plastic range, offering flexibility for integration with other ABB components such as contact blocks (e.g., 1SFA611202R110810 for single contact) and LED blocks (MLBL series), which are sold separately. The panel cutout thickness compatibility ranges from 1.5 mm (0.06 in) to 6 mm (0.24 in), accommodating a wide variety of mounting configurations. With a weight of 0.027 kg (0.06 lb) per unit, the M2SS1-31C balances performance with a lightweight design for easy installation and maintenance.
