Siemens 52PA8A3 Push Button

Siemens 52PA8A3 is a 30 mm green flush-mount push button from the 52P pilot-device family, designed for panel installation with a low-profile face that sits flush with the panel surface. This non-illuminated operator is shown in variants that demonstrate the family’s flexible contact configurations; for example, the 52PA8A3KP variant is green, non-illuminated, and specifies a 1NO-1NC contact arrangement, while the 52PA8A3B variant is green with 2NO-2NC contacts. The 30 mm mounting size matches standard panel cutouts, making it a common choice for control panels, machine start/stop circuits, and other automation applications where a compact, color-coded pushbutton is required. When selecting this part, verify the exact contact configuration and mounting finish to ensure compatibility with your wiring diagram and panel layout.
