Why Choose the ABB P9MER4RN Red 40 mm Twist-Release Mushroom Pushbutton?
The ABB P9MER4RN is a red maintained mushroom pushbutton with twist release from ABB's P9M modular metal pilot-device range. Supplied under ABB order code 1SFA184071R9001 and belonging to the P9M Pushbuttons product group, it provides a prominent manually operated control for industrial machinery and operator stations.
The P9MER4RN features a 40 mm diameter red mushroom head with maintained operation. Once actuated, the operator remains in its operated position until deliberately reset using the twist-release mechanism, making it suitable for control functions where a retained mechanical state and intentional manual reset are required.
Designed for a standard 22 mm mounting hole, the P9MER4RN combines ABB's modular metal construction with IP66 front-side protection. Each reference includes the satin chrome metal body and nut together with the holder, while compatible ABB contact blocks can be selected according to the required electrical switching arrangement.

Maintained mushroom pushbuttons remain mechanically actuated after being pressed, making them suitable for control functions where the selected state must remain until a deliberate reset is performed. The P9MER4RN uses a twist-release mechanism, requiring the red mushroom operator to be rotated before the maintained mechanism returns to its normal position.
The ABB P9MER4RN combines this operating principle with a prominent 40 mm red mushroom head, standard 22 mm panel mounting and IP66 front-side protection. Its modular P9M construction allows compatible contact blocks to be selected separately to create the electrical contact arrangement required by the machinery or control system.
Typical Applications
- Industrial machinery control panels.
- Maintained machine-command functions.
- Manufacturing and production equipment.
- Mining and heavy-industry machinery.
- Construction equipment control systems.
- OEM machinery and industrial operator stations.
