The explanation of the DIP switches on the motherboard PCB is as follows:
1. A DIP switch is a single device consisting of a set of switches, usually mounted on a PCB or breadboard. This switch performs the most basic operation and the switch position must be set manually so its status is easily determined when the system is started.
2. DIP switches usually appear in the form of a standard dual in-line package (DIP). They can be individual switches or a complete set of switches. It is generally designed on a printed circuit board and used with other electronic components. The main purpose is to adjust the characteristics of electronic equipment.
3. DIP switches can be regarded as a substitute for jumper sets. The main advantage is that the switch is easier to switch than jumpers, and there are no shorting devices that may be lost or fallen off.
4. The simplicity, flexibility, and low cost of DIP switches have led to their continued use in many electronic applications. These switches come in a variety of sizes, configurations, styles, and power ratings. Customers can select the number of DIP switch positions based on the application's configuration requirements. Some DIP switches can be actuated by hand, others require special tools or screwdrivers to change the switch position.
