Spring Fingers
Spring ngers (also known as shield ngers, grounding springs, universal ground contacts, or clips) can be used in
all types of small printed circuit board applications across all industries. A spring nger is a single contact, surface
mountable internal connector with multiple functions on a PCB. It can be used for antenna feeds, low voltage
electrical connections or for grounding to prevent EMI noise and static caused by a speaker, motor, microphone or
any other vibration within an application. TE continues to expand its spring nger portfolio oering a broad range
of styles, heights, and materials to meet all customers needs.
