Siemens 52PR8ER Illuminated Push Pull Button With LED Indicator

Siemens 52PR8ER is a 1 3/4" (44.5 mm) plastic mushroom-head illuminated push-pull operator intended for panel mounting in control enclosures. The twist-to-release head operates as a two-position switch with 1 NO – 1 NC contacts, delivering straightforward on/off control in a compact unit. It includes an integrated LED indicator; the variant is documented as a 120 V full-voltage LED with a red LED lamp, suitable for signaling in machine control circuits. This push‑button is commonly used in industrial control panels for status indication and actuation of start/stop or signaling functions, combining visual feedback with reliable push-pull operation in a single ergonomic device.
