Description

The ABB M2SS1-30B is a 2-position, non-illuminated, maintained-action selector switch featuring a short handle and a black actuator, housed in a chrome metal bezel for a professional industrial appearance. Part of ABB’s M2 22 mm modular operator component system, this selector switch is supplied without a contact block, allowing the user to add the required combination of N.O. and/or N.C. MCB or MCBH contact blocks to match the specific circuit requirements of their application. The maintained action means the switch retains its selected position after the operator releases the handle, appropriate for on/off, start/stop, or mode selection functions.

Built to comply with IEC 60947-5-1 for industrial control circuit devices, the M2SS1-30B uses a 22 mm panel mounting diameter and is designed for installation in standard industrial control enclosures, machine front panels, and operator station boxes. The chrome metal bezel provides durability and aesthetic quality appropriate for premium machine and panel installations. The short handle design provides a compact actuator that minimises the risk of accidental operation while remaining accessible for intentional operation by the machine operator.

The M2SS1-30B is a versatile building block within ABB’s M2 modular operator system, which includes contact blocks, illumination modules, and a variety of handle styles and colours. Panel builders and machine builders can combine it with standard MCB or MCBH contact block modules to create selector switches with exactly the contact output configuration required, whether for single or multiple switching functions. This product is widely used in machine tool control, industrial process control, building services panels, and any application requiring a reliable, professional-quality 2-position maintained selector switch in a 22 mm panel format.
