The Siemens SIRIUS ACT 3SU1060-4LC01-0AA0 is a 2-position key switch head developed for secure and reliable industrial control applications. As part of the SIRIUS ACT 3SU10 series, this switch head is engineered for momentary (spring-return) operation, ensuring quick switching and immediate reset to the default position when the key is released. The design supports integration into control panels and equipment requiring authorized operation, such as electrical circuits, cabinet locking mechanisms, fire alarm systems, fuse boxes, and power isolators.

This model features a sleek, shiny metal black finish complemented by a silver high-gloss metal front ring, offering both a modern look and durability in demanding industrial environments. The switch head is equipped with a Ronis type key system, providing two individual keys for secure access control. Its 30 mm cutout diameter ensures straightforward compatibility with standard industrial panel designs.

Mechanical robustness is a hallmark of the 3SU1060-4LC01-0AA0, which offers a mechanical life of up to 300,000 cycles, supporting reliable long-term operation. The angle of throw is 45°, allowing for clear and distinct selection between the two key positions.

For use in challenging environments, the switch head offers exceptional ingress protection: IP67, IP66, IP20, IP69K, and IP69 ratings shield the mechanisms from dust, water jets, and other contaminants, enabling installation both indoors and in demanding outdoor or washdown settings. The product also complies with major international standards (CE, CSA, UL) and holds recognition for extended product life and durability, making it suitable for global industrial markets.

Typical industrial applications include manufacturing control panels, facility automation systems, utility panels, and emergency shutdown stations, where secure, authorized, and clearly defined actuation is required. Its reliability, safety, and robust construction make it an ideal choice in industrial automation, process control, and equipment safety systems.
