The Siemens 3SU10022BC100AA0 is an illuminable 22 mm round selector switch from the Siemens SIRIUS ACT 3SU1 range. It features a black plastic short selector, 2 switch positions O<I, momentary contact operation, and a 45° actuating angle with positions at 10:30h/12h. Siemens documentation identifies it as an illuminable selector switch designed for industrial commanding and signalling applications.
The selector is intended for installation in compatible industrial control panels, machine operator stations, automation equipment and electrical cabinets. Its 22.3 mm mounting-hole diameter is suited to the standardized 22 mm operator-device format.
The selector is specified with IP66, IP67 and IP69/IP69K protection ratings, making the SIRIUS ACT design suitable for demanding industrial environments. Siemens also specifies a typical mechanical service life of 1,000,000 operating cycles for this selector element.
The 3SU10022BC100AA0 industrial selector switch provides a compact rotary operator interface for switching between two defined control positions.
The black short actuator gives the panel a clean and professional appearance, while the O<I position marking allows operators to distinguish the two available switching positions.
Because the selector is momentary, it is intended for applications where the actuator returns from the center toward the left after operation rather than functioning as a permanently latched selector in that direction. Siemens specifies the operating principle as 45° momentary contact with return from center to left.
The Siemens 3SU10022BC100AA0 is an illuminable selector switch, allowing compatible illumination components to be used for visual indication.
Illuminated operator controls can help operators identify selected functions or machine conditions quickly. The SIRIUS ACT family supports different selector configurations, including illuminated and non-illuminated versions.
The exact illumination configuration should be selected according to the complete SIRIUS ACT assembly and required module configuration.
This model uses a black plastic selector and black plastic front ring. The mounting opening is 22.3 mm, while the selector element has a compact installation format suitable for panel mounting.
The selector can be combined with compatible SIRIUS ACT components to create customized operator stations for machinery and automation systems.
The Siemens 3SU10022BC100AA0 can be used for:
The 3SU10022BC100AA0 is the selector/front element, and Siemens documentation notes that it is supplied as a single device with holders and modules ordered separately where required.
Therefore, when replacing or building a complete operator-control device, verify whether the required holder, contact module and illumination module are already available or need to be ordered separately.
