Cam switch 16A, Dahlander's two-speed switch with direction of rotation change, in OB14 housing. SK16-7.8538\OB14

Universal cam switch for motor control

This 16A cam switch, which also functions as a Dahlander two-speed reversing switch, is a versatile device designed for controlling electric motors. It finds application in both industrial installations and devices requiring precise speed control. The cam mechanism-based design ensures reliable and durable operation, and the ability to change the direction of rotation increases functionality in various applications.

The switch is supplied in a robust OB14 housing, providing protection against mechanical damage and environmental influences (IP65 protection class on the front side). Panel mounting is simple and intuitive, making it easy to integrate with existing control systems.

Application and functionality

The device is ideal for applications requiring motor speed regulation, such as:

• Controlling drives of machines and industrial equipment.
• Adjusting the speed of fans and pumps.
• In applications requiring a change in the direction of motor rotation (e.g., gates, blinds).
• In building automation systems.

Design and characteristic features

The switch has been designed with durability and reliability in mind. The segmented design with double cams allows for creating any connection programs depending on the user's needs. Made of high-quality materials, it ensures long-term operation even in harsh working conditions. The Dahlander switch allows for smooth adjustment of the motor speed without the need for additional control elements. The rated continuous current of 16A and high resistance to shock loads guarantee safe and efficient operation of the device. Additionally, the presence of the "0" position provides full control over the motor power supply.
