Siemens 52PP2E2 Illuminated Push Button Switch

Siemens 52PP2E2 Illuminated Push Button Switch is a 30 mm panel‑mount mushroom‑head control from Siemens’ Class 52 family. The red actuator is illuminated, providing a clear visual cue for operators in industrial environments. Identified by model 52PP2E2, this device is documented in distributor catalogs (for example, DigiKey lists 52PP2E2AB and Mouser lists 52PP2E2), confirming its 30 mm form factor and illuminated configuration. As a 52‑series pilot device, it is designed to integrate with other Siemens pushbuttons and indicator lights in control panels, enabling consistent aesthetics and straightforward wiring in automation installations. The red illumination enhances signal visibility in low‑light facilities and among cluttered control consoles, helping operators quickly confirm the switch status during routine operation or troubleshooting. This part is commonly used in machine control stations, panel assemblies, and industrial control enclosures where a robust, clearly lit user input is required.
