Siemens 3SU1052-2BL30-0AA0 Illuminated Selector Switch, 22mm Metal Yellow, 3-Position Original Brand New

Overview

The Siemens 3SU1052-2BL30-0AA0 Illuminated Selector Switch is a premium industrial control device designed for demanding automation environments. Part of the renowned Siemens 3SU1 series, this selector switch delivers outstanding durability, precise operation, and clear visual indication. Its 22 mm mounting diameter makes it compatible with standard control panels, while the metal, shiny finish ensures long service life even in harsh industrial conditions.

This selector switch features three clearly defined positions (I-O-II) with a latching mechanism, ensuring that the selected position remains fixed until manually changed. The yellow actuator provides high visibility, making it ideal for safety-critical applications where fast recognition is essential. The integrated illumination enhances operational clarity, especially in low-light environments.

With an actuating angle of 2×45° and ergonomic switching positions aligned at 10:30h / 12h / 13:30h, the Siemens 3SU1052-2BL30-0AA0 guarantees accurate and intuitive operation.

Key Benefit

• Superior Durability: The metal shiny finish isn’t just for looks; it provides excellent resistance to oils, chemicals, and mechanical wear, making it ideal for harsh factory floors.

• Enhanced Visibility: The illuminable yellow handle ensures that operators can quickly identify the switch and its current status, improving safety and reducing operational errors.

• Precision Engineering: With an actuating angle of 2×45° (at 10:30h, 12h, and 13:30h positions), the switch provides a distinct “click” and tactile feel, confirming the transition between states.

• Ease of Installation: As part of the SIRIUS ACT line, it features a simplified installation concept that allows for one-handed mounting and snap-on components.

• Extreme Protection: Designed to meet IP66, IP67, and IP69K standards, this switch can withstand high-pressure washdowns and immersion.

Product Function

The Siemens 3SU1052-2BL30-0AA0 selector switch is engineered to control multiple operational states within electrical and automation systems. Its three-position configuration (I-O-II) allows users to switch between modes such as start/stop/select, forward/off/reverse, or similar multi-state control functions.

The latching function ensures that once a position is selected, it remains engaged until deliberately changed. This prevents accidental switching and improves operational stability. The illumination feature provides instant visual confirmation of switch status, making it easier for operators to monitor system conditions.

Application

This illuminated selector switch is suitable for a wide range of industrial and commercial applications, including:

• Industrial automation control panels

• Manufacturing machinery

• Electrical cabinets and switchboards

• Process control systems

• Conveyor systems

• Power distribution panels

• HVAC and building automation systems

Its robust design and high visibility make it especially useful in environments where reliability and operator safety are critical.
