Rotary switches serve an incredibly wide range of purposes from electronic switching to mechanical networking and more. The D2D0312S is a 12-position rotary switch offering stable contact and low-resistance. It is well-suited for high-frequency switching applications such as manual changing of frequency or level settings in electronic equipment.

The D2D0312S consists of two parts – the rotary operating element and the rear housing. The rotary operating element consists of 12 fixed positions, each has a cam which contacts a portion of the rear housing, thus completing the switch circuit. The rear housing consists of 7-8 contact bridges with electrical contacts arranged in alternative segments. The position of the rotary element therefore determines which bridging contact is connected and broken, thus producing the desired switching functions.

The D2D0312S is a high-reliability rotary switching actuator commonly used in audio and video equipment, such as volume and tone controls. It has high-frequency characteristics, low contact resistance and stable switching capabilities – making it the ideal choice for various applications that require consistent performance.

The working principle behind the D2D0312S is quite straightforward. When the rotary operating element is turned, it rotates the cam which, in turn, actuates the contact segments of the rear housing. As the elements move, they bridge and break the contact points, thus allowing a current to flow through the switch or interrupting it. By carefully adjusting the contact points, it is possible to control which output will be used when the switch is rotated.

In addition to its widespread use as a rotary switch, the D2D0312S can also be used in a variety of systems. It can serve as a level adjustment for radio equipment, temperature control for home appliances, speed adjustment for motors, and brightness adjustment for lighting systems, among many other applications.

In summary, the D2D0312S is a versatile and reliable rotary switch that is suited for high-frequency switching applications. It features low contact resistance, stable contact and high-frequency switching characteristics. It is used in various systems such as radio equipment, home appliances, motors, and lighting systems. Its working principle is based on the rotation of a cam, which in turn actuates the contact segments of the rear housing, allowing a current to flow through the switch or interrupting it.
