Availability: In stock
Overview
The Siemens 3SU1052-2BC20-0AA0 is a high-performance, illuminated selector switch actuator head from the SIRIUS ACT commanding and signaling devices series. Designed for demanding industrial environments, this component features a 22 mm round metal, shiny front ring for a premium and robust finish. It is a 2-position switch (O<I) with a momentary contact type function, meaning it returns to the center (or rest) position when released, making it ideal for jogging or temporary activation functions. The red color ensures high visibility and is often used for specific control or safety-related functions.

Function and Application
The 3SU1052-2BC20-0AA0 functions as the front-of-panel operating element for a 2-position switch. Its momentary action from the center position to the ‘I’ position (and spring return) is commonly used in control panels, machine interfaces, and electrical enclosures for tasks like:
-
Jogging/Inching: Temporary activation of a motor or conveyor system.
-
Test Functions: Activating a sequence or component momentarily for diagnostic checks.
-
Override Control: Providing a brief manual input signal.
Note: This is the actuator head only. A suitable holder (e.g., 3SU1550-0AA10-0AA0), LED module, and contact blocks (e.g., 3SU1400-1AA10-1BA0) are required to form a complete, functional control unit.
