Design and manufacturing technology of multi-position rotary switch

The multi-speed rotary switch is an important switching device that can adjust multiple different gears or positions. This kind of switch usually consists of components such as knobs, contacts, and gear mechanisms, and is used to control the opening and closing status of the circuit. Different gears correspond to different functions or connection methods, suitable for various circuit needs.

Multi-position rotary switches are usually round or cylindrical in appearance and have a rotatable control knob. The knob is marked with numbers, symbols or words to indicate the function or purpose of each gear. The mechanism of the switch is usually made of metal or plastic materials that are resistant to wear and corrosion.

The principle of the multi-speed rotary switch is based on the design of the rotating mechanism and contacts to realize the connection and disconnection of the circuit. Its basic working principles include the following:

Rotating mechanism: Different gears can be selected by rotating the knob. The mark on the knob indicates the currently selected gear. The rotating mechanism usually includes gears, cams or cycloid drives, etc., which allow the switch to rotate smoothly and be fixed in the desired position.

Contact combination: The core function of the multi-speed rotary switch is to control the connection and disconnection of the circuit through different contact combinations. There is a set of contacts on each gear to connect with other circuits. When the knob is rotated to the corresponding gear, the corresponding contact will close or open, thereby opening or closing a specific circuit as needed.

Multi-position rotary switches have important applications in a variety of fields, including:

1. Electronic device control: Used to adjust the volume, brightness, mode and other parameters of electronic devices, providing convenient operation methods.

2. Circuit selection and switching: In circuit design and experiments, it is used to select and switch different circuit connections, which is helpful for circuit testing, debugging and troubleshooting.

3. Instrument control: It can be used to control the functions and mode selection of instruments, such as adjusting the measurement range, switching display modes, etc.

4. Power system control: used to control circuit breakers, contactors and other power equipment in the power system to ensure the normal operation and safety of the power system.

The multi-position rotary switch is a flexible and practical switch device that is widely used in various fields to meet different control needs.
