Rotary switches are switches that have synchronized mechanical positions which are transferred between two electrical circuits when the knob is rotated to each new position. The rotary action of the switch provides unique advantages in providing the electrical connections required for a single control, such as selecting between multiple possible independent operations, or selecting between different circuit elements. The D3G0405N is a particular type of rotary switch.

D3G0405N is a four-wire rotary switch. Its operation principle is based on the design that two wiper contact pieces connected two different parts of the resistive wire track in one movement. The main advantages of this switch compare to other switches are excellent electrical contact, lower cost and easier installation. Moreover, this switch is specially designed for signal transmission application, it can make signal transfer reliable and accurately.

The D3G0405N’s main application field is signal transfer application. It is usually used in transmission system, telecom equipment, audio-video signal transmission and its control system, computer peripheral, car audio, household appliance and medical device. In these application areas, the rotary switch offers its advantages in signal transmission where ability of adjustable settings, reliability, and durability is required. It features excellent rotation mechanism, low contact resistance, dielectric strength and environmental suitability.

In order to work properly, the D3G0405N needs an appropriate circuit board to achieve the signal switching. First the wires of the rotary switch need to be connected to the appropriate terminals on the circuit board. The circuit board then needs to be connected to the power source. Then, when the rotary switch knob is turned, it will drive the wiper contact pieces connected two different parts of the resistive wire track in one movement, so as to complete the signal switch between two different circuits.

In summary, D3G0405N is a four-wire rotary switch which is used in signal transfer application, such as transmission system, telecom equipment, audio-video signal transmission and its control system, computer peripheral, car audio, household appliance and medical device. The device features excellent rotation mechanism, low contact resistance, dielectric strength and environmental suitability. It needs an appropriate circuit board to achieve the signal switching, and it will work by driving the wiper contact pieces connected two different parts of the resistive wire track in one movement, so as to complete the signal switch between two different circuits.
