Siemens 52PM9W2 Push Button Mushroom Oil Tight Momentary 1NO 1NC

Siemens 52PM9W2 is a 30 mm, non-illuminated, momentary mushroom-head pushbutton built for demanding industrial environments, with oil-tight and watertight sealing and a chrome-finish bezel. The red plastic mushroom cap measures 1 3/4 inches (44.5 mm) in diameter, and the operator is designed for rugged, long-life service in panel-mounted installations. This model uses a 2-position momentary configuration with 1 normally open and 1 normally closed contact (1NO-1NC), making it suitable for simple start/stop or interlock circuits on machines, conveyors, presses, and other equipment. It is UL Listed and CSA Certified, and supports NEMA 1, 3, 3R, 4, 12, and 13 enclosures, reflecting its protection against oil, water, and dust in harsh workplaces. As part of Siemens' Class 52 family, it combines a durable, corrosion-resistant build with easy integration into existing Siemens control schemes.
