Unique-Bargains 2.54mm Jumper Cap Conduit 100 Pcs Black

2.54 mm Jumper Caps for Headers

These black jumper caps fit standard 2.54 mm pin headers and come in a pack of 100 pieces. They provide a quick way to close a two-terminal connection on a circuit board or automotive wiring harness. Hobbyists and technicians use them for configuration, testing or permanent links in low-voltage projects.

Behaviour under repeated use

Each cap uses a plastic housing with metal contacts that slide onto the pins. The simple friction fit holds the connection during vibration and thermal cycling typical of automotive environments. No moving parts or springs mean the contact pressure stays consistent over many insertion cycles.

Installation notes

Push the cap straight onto the header until it seats fully; the 2.54 mm spacing matches standard pin strips so no force is needed. Misalignment can bend pins, so check orientation before pressing. The pack includes 100 units with a tolerance of plus or minus two percent, so count them if an exact quantity is critical.
