Siemens 52PP2G2A Push-Pull Illuminated Maintained Switch

Siemens 52PP2G2A Push-Pull Illuminated Maintained Switch is a 30 mm command-pushbutton unit with a chrome-plated metal bezel and a red illuminated mushroom-head lens, designed as a two-position maintained push-pull switch for industrial panels. It offers a 1NO-1NC contact arrangement in maintained operation and draws illumination from a 120 V AC supply, with the rugged metal housing described as watertight/oiltight in official listings. The complete unit is built for harsh environments, featuring heavy-duty construction that supports industrial control tasks on panels and equipment where a latched on/off indication and reliable actuation are needed. Widely documented by Siemens and distributors as a 30 mm illuminated push-pull switch, this model is commonly used in automation applications such as machine control, safety interlocks, and process lines where clear status indication and durable operation are essential.
