## Long description

The Siemens selector switch is a professional-grade control component designed for industrial automation and machinery interfaces. This three-position device, featuring an I-O-II configuration, allows for reliable manual switching of electrical circuits. Engineered as part of the SIRIUS ACT series, it combines a robust plastic construction with a functional blue design, ensuring clear visibility and ease of operation in demanding environments.
Advantages
This selector switch offers exceptional durability and reliability, meeting high standards for industrial and outdoor applications. Its design allows for simple, one-handed installation without the need for specialized tools, thanks to an innovative snap-on mounting concept. The integrated twist prevention ensures the unit remains securely in place during operation. Furthermore, the device is built to withstand harsh conditions, including exposure to dust, oils, and caustic solutions, and is even capable of enduring high-pressure jet cleaning.
Suitable for
Industrial control panels and automation systems
Manual switching of electrical loads in machinery
Outdoor control interfaces requiring high protection ratings
Applications where three-position I-O-II control is necessary
When it may not be suitable
This device is a single component and requires separate holders and contact modules for a complete installation. It may not be suitable for projects where a pre-assembled, ready-to-wire unit is required without additional assembly steps.
Key specifications
Switch positions: 3 (I-O-II)
Actuating angle: 2x45 degrees
Mounting diameter: 22 mm
Operation type: Latching
Material: High-grade plastic
Color: Blue
Design: Short selector handle
How to use
To install the switch, insert the actuator into a standard 22mm mounting hole. The integrated twist prevention mechanism secures the device in place. Once the actuator is mounted, attach the necessary contact modules and holders to the rear of the unit. The snap-on design allows for quick assembly without tools. After installation, the switch can be operated by rotating the handle to the desired I, O, or II position to control the connected electrical circuits.
What to consider before purchase
Ensure you have the compatible holders and contact modules, as these are not included with the actuator.
Verify that the 22mm mounting hole size is appropriate for your control panel layout.
Confirm if illumination is required for your specific application, as this model is illuminable but requires additional components for lighting.
Usage recommendations: For optimal performance and longevity, ensure the device is installed in a clean, dry environment where possible, although it is rated for rugged use. Regularly inspect the switch for any debris buildup if used in industrial settings to maintain smooth rotation.
