Cam switch 20A, Dahlander's two-speed switch with direction of rotation change, panel mounting, yellow-grey knob, red SK20-7.8538\P04

Dahlander switch with reversing function – a reliable choice for your installation

This two-speed Dahlander switch, with a rated current of 20A, is a solid solution for controlling electric motors. Designed for both professional and end-user applications, it offers flexibility and safety in one device. Made of high-quality plastic, it provides durability and resistance to mechanical damage. Its versatility makes it suitable for many industries and workshops.

Construction and functionality

The cam switch allows changing the direction of rotation and selecting two motor operating speeds. The design with a yellow-gray knob and a red marker ensures intuitive operation and easy identification of the switch position. Front panel mounting (IP65) guarantees protection against moisture and dust, which is particularly important in harsh industrial conditions. The possibility of indirect mounting increases the range of applications.

Application and benefits

The SK20-7.8538\P04 switch is ideal for:

• Electric motor control: Provides smooth gear and direction of rotation changes, allowing for machine performance optimization.
• Industrial applications: The robust construction and high degree of protection (IP65) make it a reliable element in demanding environments.
• Workshops and service centers: Enables precise control of mechanical devices during repairs and maintenance.
• Agricultural machinery: Ensures reliable operation in difficult field conditions.

Thanks to the ability to change the direction of rotation and select two speeds, this switch allows you to adjust the motor operating parameters to specific application needs, which translates into greater efficiency and energy savings. The rated power for AC-3 is 4 kW at 400V, making it suitable for a wide range of devices. Additionally, the lack of auxiliary contacts (normally closed, changeover and normally open) simplifies installation and system configuration.
