Spring Fingers
Spring ngers (also known as shield ngers, grounding springs, universal ground contacts or antenna 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. Spring ngers can be used for antenna
feeds, low voltage electrical connections and grounding or shielding. They are benecial in preventing EMI noise
and static caused by speakers, motors, microphones or any other type of connector that can cause vibration
within an application. TE Connectivity (TE) continues to expand its spring nger portfolio o ering a broad range
of styles, heights, and materials to meet all customers needs.
