Universal cam switch for various applications

This two-pole cam switch, also known as a Dahlander switch, is a versatile device for switching electrical circuits on and off. It is suitable for both industrial installations and public buildings where reliability and load control are required. The design allows for base mounting, making it easy to integrate with existing systems.

Construction and functionality

The switch features a solid plastic construction, providing good insulation and resistance to mechanical damage. Designed for front mounting, it has a grey knob, black in color, making it easy to identify and operate. Thanks to the two-pole Dahlander switch, it is possible to control two different circuits or change the rotational speed of a motor. The rated continuous current of 40A and the rated operating power of 20kW (for AC-3, 400V) guarantee efficient operation even under high loads. The IP65 protection rating provides protection against dust and water jets, allowing operation in harsh environmental conditions.

Key features and benefits

• Versatility: Can be used in various electrical installations – from simple lighting circuits to more complex machine control systems.
