Why Choose the ABB P9MEC4RN95 Key-Release Mushroom Pushbutton?
The ABB P9MEC4RN95 is a robust key-release maintained mushroom pushbutton designed for industrial machinery, control panels and operator stations. Part of ABB's P9M Pushbuttons modular metal range, it features a prominent red mushroom actuator and key-operated release mechanism for applications requiring maintained manual control.
The P9MEC4RN95 uses a 40 mm red mushroom actuator with maintained operation. Once actuated, the operator remains in its operated position until released using the appropriate key. This version uses ABB key code 95, providing controlled reset of the maintained operator.
Designed for a standard 22 mm mounting hole, the P9MEC4RN95 is non-illuminated and provides IP66 front protection when correctly installed. Its rugged modular metal construction is intended for demanding environments including mining, construction and heavy-industry applications.
Key Advantages
- Large 40 mm red mushroom actuator for prominent manual operation.

- Key-release mechanism provides controlled reset.
- Uses ABB key code 95.
- Standard 22 mm mounting format for industrial pilot-device installations.
- IP66 front protection for demanding industrial environments.

Controlled Reset for Maintained Industrial Controls
A maintained mushroom pushbutton remains mechanically actuated after it is pressed instead of returning automatically. On the ABB P9MEC4RN95, the operated position is released using a key, helping restrict reset to personnel with access to the appropriate key code 95.
The combination of a large red mushroom actuator, key release and ABB's modular metal construction makes the P9MEC4RN95 suitable for industrial control arrangements where a prominent maintained command and controlled manual reset are required. Compatible modular contact blocks can be selected according to the electrical switching requirements of the application.
Typical Applications
- Industrial machinery control stations.
- Maintained machine-control functions.
- Operator panels requiring controlled reset.
- Mining and construction equipment.
- Heavy-industry machinery controls.
- OEM machinery and industrial automation systems.
