Rotary Switches

Rotary switches are devices used to electronically control electrical connections between circuits, equipment, or any other device, by way of rotating a shaft or cam. The most common type of rotary switch is the D9G0423N, a compact 12-position rotary switch for general purpose applications. This type of switch is used to route electrical signals from one point to another, or to control multiple circuits from the same switch.

Application Field

The D9G0423N rotary switch is commonly used for a wide range of purposes including logic control on sensitive circuits. This includes applications such as audio amplification, telephone switching, stage lighting systems, motor speed control, home instrumentation, as well as communications systems.

High grade, sealed contacts with a mechanical life of up to 50,000 operations, make this switch suitable for use in different environmental conditions, resistant to dust and dirt, and can also be used in harsh industrial and military conditions.

Working Principle

The operation of the D9G0423N switch is simple. When rotated, the shaft or cam moves internal contacts to change their position and create the electrical connection between circuits. A variety of poles and contacts can be chosen for the switch, depending on the application and requirements. The combination of the number of poles and contacts determines the type of electrical connection that is created at each position.

The contacts of the switch are made from a high quality spring steel or silver alloy material, which is critical to its durability and longevity. The related parts of the switch, such as the terminals, housing, and knob, are made from zinc or plastic for a reliable and secure fit.

In addition, the D9G0423N is equipped with a number of features that make it suitable for a range of applications. These include a wide range of operating switches, with wide spread contacts and high contact forces, a patented interlock system that prevents switch misalignment, and a detent mechanism to ensure smooth operation.

The design of the switch makes it easy to configure and install, featuring an easy to assemble design and a wide variety of mounting options, including panel, rack, surface, and chassis mount.

Conclusion

The D9G0423N is a versatile, compact 12-position rotary switch for general purpose applications. Its high quality spring steel and silver alloy contacts make it a perfect choice for many applications such as logic control, audio amplification, telephone switching, stage lighting systems, motor speed control, home instrumentation, as well as communications systems. The patented interlock system and detent mechanism ensure smooth and reliable operation. Its wide range of operating switches and easy to assemble design make it a go-to choice for a wide variety of applications.
