Cam switch 20A, 1-0-2 switch (3-pole), in OB11 enclosure. SK20-3.8380\OB11

Cam switch – reliable switching in your installation

This three-pole cam switch, with a rated current of 20A, is a solid solution for controlling electrical circuits. The design with a 0 (off) position and high resistance to external conditions, thanks to the IP65 protection class, make it an ideal choice for both professional installers and end users. The switch is supplied in a durable OB11 plastic housing, ensuring safety and durability.

Functionality and application

The cam switch SK20-3.8380\OB11 is used for manual switching of electrical circuits. Its 1-0-2 design allows you to choose between two different circuits or disconnect the power. It is designed for surface mounting, and the screw connection of the main contacts guarantees a secure and safe connection of wires with a cross-section of 1…4 mm². It can be used in a wide range of applications – from simple home installations to more demanding industrial systems.
