Eaton M22-ES-MS1 Pushbutton Key Actuator

Product Description

The EATON M22-ES-MS1 is a key-operated pushbutton actuator designed for industrial control panel applications. This component allows operators to use a physical key to engage or disengage a control circuit, adding a layer of access control to the switching function. It is part of the M22 modular pushbutton series and mounts to a standard front panel cutout. Electricians and control panel builders install this actuator when a circuit must be locked out or restricted to authorized personnel only. The unit weighs 0.05 pounds and measures 2 inches by 2 inches by 1 inch.

This key actuator is suited for residential, commercial, and light industrial control panels where access restriction is required. Typical applications include motor control centers, machine control stations, and HVAC equipment panels where unauthorized operation of a control circuit must be prevented. The M22 series modular design allows the actuator to be paired with compatible contact blocks, making it adaptable to a range of control circuit configurations.
