£132.30
The ABB 1SFA611103R2102, product designation MP4-21G, is a durable maintained illuminated pushbutton operator designed for industrial machinery, automation panels and electrical control systems. As part of the ABB modular plastic pilot device range, it combines dependable manual control with clear visual indication.
This pushbutton features an extended green actuator that remains in its selected position after operation. Its maintained action makes it suitable for commands that need to remain active until deliberately changed, while the illuminated design enables clear equipment or process-status indication when assembled with a compatible LED block.
Designed for standard 22 mm panel mounting, the MP4-21G has a chrome-effect plastic bezel and modular construction. It is supplied without a contact block, allowing the required holder, switching contacts and illumination block to be selected separately for the application.
Maintained pushbuttons remain in their operated state after being pressed, making them suitable for functions that must remain selected without continuous pressure. The illuminated green actuator can also provide a clear visual indication that the associated machine function, process or operating condition is active.
The ABB modular pilot device system allows the MP4-21G to be combined with separately selected holders, contact blocks and LED blocks. This flexible arrangement enables panel builders to create the required switching and illumination configuration while maintaining a consistent operator interface.
