The Siemens SIRIUS ACT Series Momentary Push Button Switch, model 3SU1050-3AB61-0AK0, is engineered for demanding industrial automation applications. Featuring a robust construction with black and white oval push buttons, this unit is designed for precise control and reliability in complex machinery or systems environments. The 22 mm panel cutout size ensures compatibility with standard control panels, making it an ideal component for new installations or upgrading existing systems.

The actuator employs a momentary mechanism, providing a tactile response with immediate reset upon release, suitable for stop/start or manual signaling operations. The dual-color scheme offers improved operator clarity, while the high-contrast I/O marking further increases intuitive usability. The sturdy plastic construction delivers both durability and high ingress protection, with certifications rated IP66, IP67, and IP69K, making the device resistant to dust, water jets, and high-pressure cleaning. As such, it is well-suited for harsh manufacturing environments, food and beverage processing, and automation lines where stringent hygiene or uptime is required.
