abb maintained clear illuminated extended push button 22mm mp4-21c

Why Choose the ABB MP4-21C Illuminated Pushbutton?

The ABB 1SFA611103R2108, product designation MP4-21C, 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 clear 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 clear illuminated lens allows the colour of a compatible LED block to provide the required visual indication.

Designed for standard 22 mm panel mounting, the MP4-21C 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.

Key Advantages

• Reliable maintained pushbutton operation for persistent control commands.
• Clear illuminated actuator supports flexible status indication.
• Extended actuator provides prominent and convenient operation.
• Standard 22 mm mounting format simplifies panel installation.
• Modular construction allows the contact and illumination configuration to be customised.
• Chrome-effect plastic bezel provides a clean industrial appearance.

Maintained Control with Flexible Visual Indication

Maintained pushbuttons remain in their operated state after being pressed, making them suitable for functions that must remain selected without continuous pressure. The clear actuator allows the illumination colour of the installed LED block to remain clearly visible to the operator.

The ABB modular pilot device system allows the MP4-21C 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.

Typical Applications

• Industrial machinery control panels.
• Automation and production equipment.
• Motor and process control stations.
• Operator consoles and control desks.
• Equipment-status and function controls.
• OEM electrical equipment and panel building.
