Description

The ABB MP1-31R is a 22 mm flush-head, illuminated pushbutton with a red actuator and chrome metal bezel, forming part of ABB’s M2 modular operator component system. The illuminated red actuator combines a stop or off command function with simultaneous visual indication, providing both a pushbutton and a pilot light function within a single 22 mm panel aperture. This dual function is particularly efficient in space-constrained panel layouts. No contact block is included; MCB or MCBH contact blocks are attached separately to configure the required switching outputs.

Built to IEC 60947-5-1, the MP1-31R uses standard 22 mm panel mounting and is designed to accommodate an integral illumination module alongside the pushbutton mechanism. The red colour conforms to IEC convention for stop, off, and alarm functions. The chrome metal bezel provides durable, premium-quality construction appropriate for high-specification industrial machine and control panel applications. The flush head profile reduces the risk of accidental actuation, an important consideration for stop and off command functions in machine safety design.

The MP1-31R is used in motor control panels, machine tool and process automation operator interfaces, pump and fan control stations, and building services boards where red illuminated pushbuttons are required for combined stop and status indication functions. As part of ABB’s M2 modular system, it integrates with MCB, MCBH, and illumination modules, supporting comprehensive and co-ordinated operator panel design. Panel builders and machine manufacturers find the combined illuminated pushbutton format a cost-effective and space-saving solution for start/stop circuits with integral indication.
