Why Choose the ABB P9MET4LL1 Illuminated Mushroom Pushbutton?
The ABB P9MET4LL1 is a robust maintained illuminated mushroom pushbutton designed for operator control and signalling in industrial machinery, control panels and automation systems. Identified by ABB order code 1SFA184566R9104, it forms part of the ABB P9M Pushbuttons modular metal range and features a blue 40 mm mushroom actuator with a satin chrome metal body.
This operator combines maintained operation with a pull-release mechanism, meaning the mushroom head remains mechanically actuated after being pressed and is reset by pulling the actuator. Its illuminated blue head provides prominent visual identification, while the modular construction allows compatible ABB P9 contact blocks and illumination components to be selected according to the requirements of the control circuit.
Designed for 22 mm industrial panel mounting, the P9MET4LL1 features a 40 mm diameter mushroom head, IP66 front protection and an operating temperature range of -30 to +70 °C. Each reference includes the satin chrome metal body and nut together with the holder, providing a durable modular operator assembly for demanding industrial applications.

Maintained Mushroom Control for Industrial Machinery
Maintained mushroom pushbuttons provide a large and easily operated control surface while retaining their actuated state until deliberately reset. The P9MET4LL1 uses a pull-release mechanism, so pressing the 40 mm mushroom head mechanically maintains the selected state and pulling the actuator releases it. This makes the operator suitable for machine and process functions requiring deliberate actuation and deliberate manual reset.
The ABB P9M modular metal range is designed for demanding applications including mining, construction and heavy industry while retaining the flexibility of a modular pilot-device system. The P9MET4LL1 can be combined with compatible ABB P9 contact blocks and illumination components to create the electrical switching and visual indication arrangement required by the machine or control system.
Typical Applications
- Industrial control panels and operator stations.
- Maintained machine and process-control commands.
- Functions requiring deliberate pull-to-release resetting.
- Manufacturing and production machinery.
- Mining, construction and heavy industrial equipment.
- OEM machinery and automation systems.
