In a nutshell, the role of DIP switches is to allow users to control the flow of electricity around a printed circuit board (PCB), expansion card or other electronics/computer peripheral, and therefore change the operating mode of a device.

All types of DIP switch are widely deployed across various industries and applications today, including such uses as:

PC expansion cards Arcade machines Automatic garage doors Measurement and test devices Industrial sectors and machinery controls Production and editing equipment
