Siemens 52PP7ESUBW Green Mushroom Head Push Button

The Siemens 52PP7ESUBW is a green mushroom-head push-button operator in Siemens’ 52 Pushbutton Units and Indicator Lights family, designed for rugged industrial control panels where a three-position push-pull input is required. This 52PP7ESUBW configuration is specified as 3-position (3POS) with maintained action (MTD) and is rated for 120 V operation in the documented variants of the 52PP7 series. The actuator is a round mushroom head, colored green, with Siemens catalog entries confirming green mushroom-head caps in the 52PP7-series sub-type pushbuttons, and the mushroom head is plastic in the common 52P family. In industrial control architectures, these push-buttons are used for start/stop and mode-selection tasks on control panels, with reliability features suited to demanding environments such as oil-tight or watertight mounts.
