Siemens 52PP2A2A Push Button Switch Maintained Red 2 Position

Siemens 52PP2A2A is a 30 mm, non-illuminated push/pull switch featuring a red mushroom-head actuator that provides two stable, maintained positions for hands-on control of equipment and processes in industrial panels, allowing operators to latch the circuit in either the on or off state without continuous pressure. The device is part of the 52 series of pilot devices and uses a metal housing with a 1NO-1NC contact arrangement rated for 120V operation, enabling simple start/stop and interlock circuits in standard control panels; the 1NO-1NC configuration supports separate normally open and normally closed circuits within a single operator package. Maintained action ensures the switch remains in its selected position until moved again, which is ideal for safety interlocks and sequencing in machinery, and this push/pull mushroom head is commonly used alongside other Siemens 52-series devices to create compact, reliable operator panels.
