Siemens 3su1150-0ab10-3fa0 Pushbutton

Siemens 3SU1150-0AB10-3FA0 Pushbutton is a 22 mm round, metal, black pushbutton with a flat, momentary actuator designed for heavy-duty control panels. It provides a dual-contacts configuration: 1 normally open (NO) and 1 normally closed (NC) contact, wired via a spring-type terminal for secure, vibration-resistant wiring. The actuator measures 29.45 mm in diameter and fits standard 22 mm cutouts, with a high-gloss metal front ring and a plastic actuating element in black. Rated for AC/DC operation, it carries an insulation voltage of 500 V and a surge resistance of 6 kV, suitable for control circuits, start/stop interlocks, and signaling in industrial automation. The device is protected to IP66, IP67, and IP69K, making it resilient to dust and high-pressure wash environments, and is compatible with Siemens SIRIUS ACT 3SU11 family components. Labeling options include laser-etching or inscription on the front for clear identification. This compact 22 mm pushbutton offers a robust, space-efficient input for demanding machines and panels where both NO and NC contacts are required in a single actuator.
