Allen-Bradley 800ES-MT4 Pushbutton Operator Mushroom Twist Push-Pull

Allen-Bradley 800ES-MT4 is a red, 40 mm mushroom-head pushbutton operator designed for twist-to-release action in industrial control panels. The MT4 designation identifies a 40 mm mushroom actuator with twist-to-release operation, aligning with Rockwell Automation’s 800-series pushbutton family. This compact actuator is intended for rugged panel mounting and is designed to be used with compatible 800-series contact blocks and mounting accessories to form a complete pushbutton assembly. In automation practice, the red actuator color commonly signals a critical or safety-related function, helping operators quickly locate the appropriate control point within a panel. The MT4 twist-to-release mechanism provides deliberate actuation, making it suited for applications where affirmative user input is required before the circuit is re-engaged.
