Cam switch 10A, Dahlander two-speed switch, in OB11 enclosure. SK10-4.8390\OB11

Universal cam switch for various applications

This two-pole cam switch, also known as a Dahlander switch, is a robust and reliable solution for controlling motors and other electrical devices. Designed for durability and ease of use, it is suitable for both industrial installations and home applications. The OB11 housing provides high resistance to external conditions, and the design allows for safe and efficient circuit switching.

Construction and application

The switch is designed for surface mounting and features screw connection of the main contacts. Its design based on a knob ensures intuitive operation and precise setting. The Dahlander switch allows you to change the direction of rotation of the motor or select different operating modes of the device. Thanks to the presence of the "0" position, it is possible to completely disconnect the circuit, which increases safety during maintenance or repair. The IP65 protection class guarantees resistance to dust and water jets, allowing it to be used in harsh environmental conditions.
