Siemens 52PM8A3A Push Button Momentary Green Oil Tight

Siemens 52PM8A3A Push Button Momentary Green Oil Tight is a 30 mm, non-illuminated complete pushbutton unit from Siemens’ Class 52 family, designed for demanding industrial panels. The round, flush-cap operator sports a chrome finish with a green plastic actuator cap, built for heavy-duty, water-tight and oil-tight service in harsh environments. It provides a two-position momentary action with a 1NO-1NC contact configuration, returning to the rest state after actuation. The unit is UL-listed with A600/P600 ratings and CSA-certified, and it supports NEMA 1, 3, 3R, 4, 4X, 12, 13 enclosures, making it a robust choice for control circuits in machinery and process systems. This complete pushbutton unit is ideal for panel-mounted start/stop functions, local control in wet or oily settings, and other applications where a durable green, non-illuminated pushbutton is required without any indication lighting. It uses a flush-cap plastic operator and is built for corrosion resistance and long-term reliability in challenging environments.
