Copper Jumper

A jumper is a small electrical component used to connect or disconnect circuits on a PCB (Printed Circuit Board) or breadboard. It acts as a temporary or permanent electrical bridge between two points.

1. Jumper Wire

   • Flexible insulated wire with connectors at both ends
   • Used on breadboards and prototyping circuits
   • Available with male-to-male, male-to-female, and female-to-female connectors
   • Common in Arduino, Raspberry Pi, and DIY electronics

2. Jumper Shunt (Shorting Jumper Cap)

   • Small plastic cap with metal contacts inside
   • Used to configure settings on PCBs, motherboards, and devices
   • Common in BIOS settings, hard drives, and industrial equipment

3. PCB Jumper Solder Bridge

   • A soldered connection between two PCB pads
   • Used in circuit modifications and repairs
   • Acts as a permanent electrical link

4. Automotive & Heavy-Duty Jumper Wires

   • Thick insulated wires with alligator clips or clamps
   • Used in car batteries (jumper cables) and heavy-duty electrical connections

✔ Electronics Prototyping – Used on breadboards and test circuits
✔ Computer Motherboards & Hard Drives – Configuration settings (e.g., enabling/disabling features)
✔ Automotive Circuits – Battery jump-starting and wire bridging
✔ Industrial Equipment – Temporary electrical bypasses.
