Rotary switches are widely used in electronic and electrical applications to control the connections of electrical circuits. In particular, 71A30-02-1-12S-C rotary switches are an important type of rotary switches, providing high levels of reliability and flexibility. This article will discuss the application fields and working principle of the 71A30-02-1-12S-C rotary switch.

Application Fields

The 71A30-02-1-12S-C rotary switches are mainly used in CCTV, video, audio, and industrial control systems. In CCTV systems, rotary switches are used for controlling the video inputs, connecting the field of view to different video modules. They are also used for setting different video qualities such as contrast, brightness, and more. In video applications, rotary switches are employed for controlling the audio inputs, audio outputs, volume control, and more. Additionally, 71A30-02-1-12S-C rotary switches are used in industrial control systems, such as automation systems, for controlling the speed and accuracy of machine operations.

Working Principle

The 71A30-02-1-12S-C rotary switches feature a single control component with a variety of connection options. The knob of the switch is connected to a shifting shaft, which is connected to a contact assembly with various connections. As the knob is rotated, the shifting shaft moves the contact assembly, allowing the rotary switch to connect different components of the circuit. The ability to transfer the connection between different parts of the circuit makes the rotary switch an attractive option for electrical applications.

The 71A30-02-1-12S-C rotary switch contains a series of contacts which are Beryllium-Copper based, and feature silver plated contacts to minimize contact resistance. The contacts are further secured by a selected cover, which protects them from dust and debris. The switch also features a threaded mounting for increased stability and flexibility.

The 71A30-02-1-12S-C rotary switch is a single-pole, triple-throw design, which means it is capable of connecting different circuit components to three separate circuits. The three positions of the switch can be connected to different circuits, allowing it to transfer the connection as the knob is turned. The switch is able to detect the current levels of each component, allowing it to effectively transfer the connection between different circuits.

The 71A30-02-1-12S-C rotary switches offer high levels of reliability and flexibility, making them an ideal choice for electronic and electrical applications. They are available in a variety of styles, allowing them to be used for many different types of applications. Additionally, the use of a single control component and silver-plated contacts ensures that the switch offers a reliable and efficient connection for any application.
