Jumper

Jumper is a tiny electrical device which is used to close or open part of an electronic circuit. It can be used as an alternative to a DIP (dual in-line package) switch. A jumper is made of two or more electrically conductive jumper pins and jumper box. The set of electrically conductive pins is separated from each other by a plastic material. The jumper box is made up of an electrically conductive material which easily allows electric current through it and this electrically conductive material is covered with a non-conductive plastic block to prevent accidental short circuits. These are two pin jumpers (also called shunts) that will create an electrical connection between two pin headers. Commonly used to modify settings on a board or device.
