Siemens SIRIUS ACT 3SU10022BC100AA0 Selector Switch Head, 22mm, 2-Position, Latching, Black Plastic Front Ring, Illumination Capable

In industrial control panels, operators need a reliable way to switch between two circuits with a simple twist. The Siemens 3SU10022BC100AA0 selector switch head, part of the SIRIUS ACT series, provides a robust 22 mm mounting solution with a black plastic front ring and a short black selector knob. It offers two switch positions with a 45-degree switching angle and latching (maintained) operation, ensuring the selected position stays until manually changed. The front ring is made of plastic and can be illuminated, allowing for status indication when paired with compatible LED modules. The holder is included, simplifying installation into standard 22 mm panel cutouts. With a front degree of protection of IP66, IP67, and IP69K, it withstands harsh washdown environments, and its mechanical endurance of 10 million switching cycles ensures long-term reliability.

Why choose it

This selector switch head is engineered for demanding industrial applications where reliability and durability are critical. The high IP ratings and wide temperature range make it suitable for use in harsh environments, while the illumination capability provides clear visual status indication. The latching mechanism ensures stable switching positions, reducing the risk of accidental changes.

Ideal use cases

• Control panels for machine tools and production lines
• Conveyor systems requiring mode selection
• Packaging machinery with two operational states
• Industrial automation systems needing manual override

Good to know

The holder is included with the switch head, simplifying assembly. For illuminated operation, a compatible LED module and contact block are required (sold separately). The front ring is made of plastic, offering a lightweight yet robust solution for panel mounting.
