To use these jumper bars, simply align the opening of the plug with the desired pair of pins on your header. Press the jumper firmly onto the pins until it is fully seated to ensure a solid electrical connection. When adjustments are needed, pull the jumper straight off the pins using your fingers or a small pair of needle-nose pliers.
What to consider before purchase
Verify the pin pitch of your hardware matches the 2.54mm standard
Ensure the open-type design meets your specific insulation requirements
Confirm the quantity is sufficient for your project scope
For optimal performance, ensure that the pin headers are clean and free of oxidation before installing the jumper bars. Avoid repeated bending of the pins to maintain a secure fit over the lifespan of the device.
