Dip switches (DIP switches) are widely used in many electronic devices, especially in situations where users need to manually configure settings. The following are some common devices and fields that often use dip switches:

1.Embedded systems and development boards

• Embedded controllers : Many embedded systems and development boards (such as Arduino, Raspberry Pi, etc.) use dip switches to set the device's operating mode, address, or other functions.
• Hardware debugging and testing : Developers can configure debugging modes, select different boot modes, etc. through DIP switches.

2. Computer Hardware

• Motherboard : Some computer motherboards use dip switches to adjust system settings, such as jumper settings (e.g. boot order of hard drives, BIOS settings, etc.).
• Hard disk drive : Early hard disk drives, floppy drives, and other devices used dip switches to configure the device address or mode.

3. Home appliances

• Air conditioners and refrigerators : Some air conditioners and refrigerators have internal control panels that use dip switches to set temperature, operating mode, etc.
• Power metering equipment : Some power meters, thermostats, etc. use dip switches to configure parameters.

4. Communication equipment

• Routers and switches : In network devices, dip switches can be used to set the device's operating mode, select operating frequency, IP address segment, and other configurations.
• Wireless communication devices : such as radio transceivers, may use dip switches to select channels, frequencies, etc.

5. Test and measurement equipment

• Oscilloscopes and spectrum analyzers : In some test equipment, dip switches are used to select different test modes, ranges, or set frequencies.
• Digital multimeter : A digital multimeter usually uses a dip switch to select the measurement mode (current, voltage, resistance, etc.).

6. Industrial automation equipment

• PLC (Programmable Logic Controller) : In industrial automation, PLC systems often use dip switches to set the operating mode or address of the device so that it can be configured in the system.
• Sensors and actuators : Some sensors and actuators are equipped with dip switches to facilitate users to set operating parameters or adjust sensitivity.

7. Audio and video equipment

• Audio equipment : Some audio processing equipment, mixers, amplifiers, etc. use DIP switches to select input sources, audio channels, etc.
• Video equipment : Video switchers, video distributors and other equipment also often use dip switches to select modes or channels.

8. Gaming equipment and entertainment electronics

• Game consoles and controllers : Some early game consoles and peripherals used dip switches to set game modes, channel selection, etc.
• Analog Gaming Devices : Some analog gaming hardware uses dip switches to select different game options or game settings.

9. Automotive electronics

• Car audio systems : Some car audio equipment or navigation systems use dip switches to select operating modes or configurations.
• Vehicle control system : Some vehicles' onboard control systems (such as the engine control unit ECU) may use dip switches for simple configuration.

10. Consumer Electronics

• Printers and copiers : Early printers or copiers may have used dip switches to set the device's operating state or mode.
• Game consoles : Some old-fashioned game consoles or home appliances use dip switches to switch between different working modes or signal settings.

The advantages of dip switches are simplicity, reliability and ease of operation, which are very suitable for occasions where settings do not need to be changed frequently. Therefore, dip switches are still widely used in equipment that requires fixed configuration and simple settings.
