A jumper is a small connector that connects two contacts or contact pins. It is manually plugged onto pins and forms a contact bridge.
Jumpers are usually covered with a plastic layer that serves as electrical insulation and offers protection against contact. This also prevents highly sensitive electronic components from being damaged by electrostatic discharges
can beconfigured, memory areas can be switched or certain operating states
can be defined. Theposition at which the jumpers have to be plugged in can be found in the respective operating instructions.
In circuit board manufacturing, solder bridges are called jumpers. These are unwanted solder connections between closely spaced tracks or solder points.
