Grounding contacts are surface mountable internal connectors used for circuit grounding (a return path for electric current) of SMT (surface mount technology) devices.

### How do grounding contacts work?

Grounding contacts work by providing an electrical connection while also providing protection from static and EMI (electromagnetic interference) noise between a PCB (printed circuit board) and other electronic components, such as speakers, internal antennas, shield cams or secondary PCBs.

Grounding contacts come in a broad array of styles, sizes and heights, to ensure efficient EMI protection and contact. When mounted in a row, they can be used as an RFI (radio-frequency interference) shielding connection for [cabinet enclosures](/web/c/safety-security-esd-control-clean-room/esd-control-clean-room/esd-safe-cabinets-drawers-inserts/) and metal boxes. They are designed to maintain positive contact with the mating surface and allow for both sliding and wiping action.

### Applications of grounding contacts

Grounding contacts are used in virtually every small PCB application. Some of the typical applications include:

- MP3 players
- Smartphones
- GPS units
- Tablets
- PCs and laptops
- Automotive
- Industrial equipment
- eReaders
- Home electronic devices
- Video and digital cameras
