The most common type of jumper is a small plastic tab containing two sockets spaced 0.1 inch (2.5 mm) apart. The jumper fits over and shorts together pins on a header fitted to the PCB. It acts as a low-cost substitute for a switch, where the connection needs to be made only rarely made. A DIP switch performs the same function. There is no standard schematic symbol to represent a jumper.
