Cam switch 10A, Dahlander two-speed switch, base rail mounting front grey knob black SK10-4.8390\BS23

Cross switches – reliable circuit switching

This two-speed cross switch, also known as a Dahlander switch, is a robust solution for controlling electrical loads. Designed for both professional and demanding end-user applications, it provides safe and efficient circuit switching. The design allows for changing the direction of rotation of motors or selecting different speeds, making it a versatile element in many installations.

Construction and application

The SK10-4.8390\BS23 switch is characterized by its rail mounting (TS35), which facilitates its integration with existing distribution systems. The front of the switch has an IP65 protection rating, which guarantees resistance to dust and moisture – an ideal solution in harsh industrial conditions. The black knob provides convenient operation and precise setting of the switch position. The device has a "0" position, which allows for complete disconnection of the circuit.

Advantages and product features

• Versatility: The Dahlander switch allows you to change the direction of rotation or select two different motor speeds, increasing the functionality of the installation.
• Durability: Made of high-quality plastic, it ensures long-lasting and reliable operation.
• Safety: The IP65 protection rating protects against environmental influences, minimizing the risk of failure and ensuring safe use.
• Easy installation: Rail mounting (TS35) significantly speeds up installation and facilitates integration with existing systems.
• Suitable for loads: The rated power for AC-3 is 3 kW at 400 V, and the rated continuous current is 10 A, allowing it to operate a variety of electrical devices.
• Solid construction: The lack of normally open and normally closed auxiliary contacts simplifies the design and increases the reliability of the device.
• Universality: Suitable for indirect mounting, providing flexibility in choosing the installation location.

Technical parameters in practice

A rated continuous current of 10A and a rated power of 3kW at 400V make the switch suitable for controlling medium-power motors and other electrical devices requiring reliable circuit switching. Screw connection of the main contacts ensures a secure and durable connection of the wires. The design without a return position to "0" means that the switch remains in the selected position until the setting is manually changed – this is important in applications requiring a stable circuit state.
