Spring Fingers

TE Connectivity AMP Connectors

Spring fingers (also known as shield fingers, grounding springs or universal ground contacts) are used in almost every small printed circuit board application. A spring finger is a single contact, surface mountable, internal connector. It provides an electrical connection and grounding from EMI noise and static between a PCB and other electronic components, such as a secondary PCB, shield cam, antenna, or speaker. TE Connectivity offers a wide selection of spring fingers in varying styles and sizes depending on the type of application.
