DIP switch uses

DIP switches are less widely used today than they once were, due greatly to the trend for downscaling and the falling costs for other comparable solutions (for example selecting device output options through built-in software control). However, they're still fairly commonplace in a wide range of industrial applications and test circuits.

This is because manual DIP switches offer an rather cost-effective option for device control, and one that's also very easy to wire into an existing PCB or breadboard circuit design model. DIP switches also offer a quick and convenient way to physically see what settings are currently selected without having to power the system on first, and can drastically reduce the need for further expenditure on additional hardware to perform a wider range of output tasks.

Common applications for DIP switches in modern devices and circuits include:

Configuration of a wide range of options on PC hardware and peripherals

This includes motherboards, video cards, hard drives, modems, expansion modules and other accessories or auxiliary components

DIP switches are still widely found on garage door opening mechanisms

They're commonly used in universal/multi-device remote controls to prevent electrical interference leading to accidental control of an unintended device

In this case, the DIP switch will be used to set a different radio frequency for each pairing of transmitter and receiver
