Universal Contact

Spring fingers (also known as shield fingers, grounding springs, universal ground contacts, or clips) can be used in all types of small printed circuit board applications across all industries. A spring finger 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. Sunway continues to expand its spring finger portfolio offering a broad range of styles, heights, and materials to meet all customers’ needs.
