## Long description

The Siemens 3SU1002-2BF20-0AA0 is a professional-grade 2-position selector switch designed for reliable manual control in industrial automation systems. This round, 22 mm diameter switch features a durable red plastic actuator and is engineered for high-performance operation in demanding environments. As part of the SIRIUS ACT series, it offers a robust solution for switching and controlling electrical loads with precision and ease.
Advantages
This selector switch benefits from an innovative snap-on installation concept that allows for quick, one-handed mounting without the need for specialized tools. The design includes integrated twist prevention, ensuring the unit remains securely in place during operation. Its high degree of protection makes it resistant to dust, oils, and caustic solutions, and it is even capable of withstanding high-pressure jet cleaning, making it suitable for both indoor industrial settings and outdoor applications.
Suitable for
Industrial control panels and machinery operation
Automation systems requiring manual switching
Outdoor equipment control units
Electrical load management
This selector switch may not be suitable for applications requiring more than two switching positions or for environments where a non-latching (momentary) operation is specifically needed, as this model is a latching type. Additionally, it is a single component, so it may not be suitable if you are looking for a complete, pre-assembled unit including holders and contact modules.
Key specifications
Actuator type: Short selector switch
Switch positions: 2 (O-I)
Operation type: Latching
Actuating angle: 90 degrees
Mounting diameter: 22 mm
Material: High-grade plastic
Color: Red
Installation is straightforward due to the snap-on design. Simply insert the switch into a standard 22 mm mounting hole. The integrated twist protection ensures correct alignment without additional components. Please note that this product is a single device; you must purchase the corresponding holders and contact modules separately to complete the installation and wiring process.
What to consider before purchase
Ensure your control panel has a standard 22 mm mounting hole
Verify that a 2-position latching function meets your circuit requirements
Remember to order the necessary holders and contact modules separately
Check if your system requires illumination, as this unit is illuminable but modules are sold separately
For optimal performance and longevity, ensure the device is installed according to the manufacturer's technical documentation and that all connections are properly secured to prevent vibration-related issues.
