Jumpers

Jumpers are short, insulated connectors used to create temporary or permanent electrical connections between two points on a circuit board or chassis. They typically consist of a metal bridge or pin enclosed in plastic or rubber insulation, allowing current to pass when placed between two contacts. Jumpers are often used during testing, configuration, or troubleshooting to modify circuit functionality without soldering. They are simple, cost-effective solutions for establishing or altering electrical connections quickly and easily, making them common in electronics assembly and repair.
