Description

The ABB MP1-31G is a 22 mm flush-head, illuminated pushbutton with a green actuator and chrome metal bezel, part of ABB’s M2 modular operator component system. The illuminated green actuator provides both a clear run or start command interface and a simultaneous visual indication that the circuit is active, combining the functions of a pushbutton and a pilot light in a single 22 mm panel position. The green colour follows IEC convention for start and run functions. No contact block is included; MCB or MCBH contact modules are added separately to configure the required switching outputs for the illuminated pushbutton circuit.

Compliant with IEC 60947-5-1, the MP1-31G accepts standard 22 mm panel mounting and is designed to combine an integral illumination module with the pushbutton actuator mechanism. This dual function is particularly valuable in applications where panel real estate is limited and where a single device must serve both as a start command and as a status indicator. The chrome metal bezel ensures mechanical durability appropriate for industrial panel environments, and the flush head design minimises accidental activation risk.

The MP1-31G is widely used in motor control panels, machine tool operator interfaces, process plant control consoles, and building services control boards where green illuminated pushbuttons are specified for combined start and run indication functions. As part of ABB’s M2 operator system, it integrates with MCB and MCBH contact blocks and other M2 components for consistent panel design. Panel builders and machine manufacturers specify the MP1-31G where the combination of pushbutton command and integrated visual status indication in a compact 22 mm format offers significant advantages in panel design efficiency.
