Eaton M22-PV/KC11/IY Emergency Stop Mushroom Pushbutton, Red, 1NO/1NC, IP66, 22.5mm

In a busy automotive assembly line, a sudden jam on the conveyor demands immediate shutdown. The Eaton M22-PV/KC11/IY emergency stop mushroom pushbutton sits right at the operator's station, its red mushroom head impossible to miss. One firm press latches the contacts open, cutting power to the drive motors and bringing the line to a safe halt. Only after clearing the jam and twisting or pulling the button to release does the circuit re-close, preventing accidental restart. This is the essence of reliable emergency stopping in industrial environments.

With a long mechanical life and compliance to international standards, it delivers reliable safety performance in demanding applications. The modular design allows seamless integration into existing control panels, and the screw terminals facilitate quick and secure wiring.

Ideal use cases

• Emergency stop stations on factory machinery and production lines
• Conveyor systems in material handling and logistics
• Automated packaging and processing equipment
• Machine tools and CNC workstations
• Any industrial control panel requiring a latching E-stop with IP66 protection

Good to know

The M22-PV/KC11/IY is part of the modular Eaton M22 range, allowing you to combine it with other contact blocks, LED elements, and enclosures to build a complete control solution. The pull-to-release mechanism requires a deliberate action to reset, adding an extra layer of safety. Installation is straightforward with a standard 22.5 mm panel cut-out and M20 cable entry. Note that the button is supplied unlit, but compatible LED elements can be added if visual status indication is needed.
