Acronym for Dual Inline Package Switch. A compact electric switch with a slider that may be set to “on” or “off.” Because of the small form factor, arrays of multiple DIP switches can easily be incorporated into one package. This type of switch is designed to be used on a printed circuit board along with other electronic components and is commonly used to customize the behavior of devices such as mic preamps, equalizers, mixer inputs, and other specific applications. DIP switches are often used instead of jumper blocks in situations where a setting may need to be changed more than once.
