Allen-Bradley 800EM-MJ4 Jumbo Mushroom Pushbutton

Allen-Bradley 800EM-MJ4 is a 60 mm jumbo mushroom pushbutton from the 800E IEC-style family, designed as a back-of-panel, non-illuminated operator. The MJ4 designation identifies the jumbo-size mushroom head, intended for high-visibility actuation in control panels or machine interfaces where a large, glove-friendly input is beneficial. This model is a non-illuminated, momentary-contact pushbutton (as with other 800E mushroom operators) and is typically used with standard 800E contact blocks to configure simple NO/NC circuits for start/stop or reset functions in industrial equipment. Built for rugged environments, the 800EM-MJ4 provides a durable, field-installable option that can be integrated alongside other 800E components within a single panel architecture. When ordering, consider pairing with compatible mounting hardware and contact blocks to complete the control circuit and ensure reliable panel operation across multiple machines or lines.
