DIP switches (also known as address switches) are miniature switch arrays that implement binary coding through physical toggling. Their core principle relies on the connection and disconnection of mechanical contacts. Each independent switch unit achieves parameter configuration or function selection through its “on/off” state (corresponding to binary “1/0”).

DIP switches are primarily categorized into three types: flat-style, piano-key style, and IC-type. By mounting method, they are divided into through-hole, side-entry, and surface-mount types. By pitch, they are classified as 2.54mm and 1.27mm.

DIP Switch primarily used in handheld electronic devices and portable computers，instrumentation and controls，address switching for industrial controls，computers and peripherals (logic switching, data storage devices)，automation components (such as timers)，function controlling in numerous applications，security functions (alarms, access controls, smoke detectors)
