A Metal Dome Sheet is a key switching component used between various circuit boards, including PCBs and FPCBs, and silicone rubber keypads.

Through direct contact with the metal domes, it transmits electrical signals and controls the opening and closing of electrical circuits. It also provides a distinctive tactile click, delivering a responsive and satisfying user experience.

Designed as a next-generation switching solution that addresses the limitations of conventional membrane and poly-dome switches, Metal Dome Sheets offer excellent durability and reliable switching performance.

The sheet consists of a polyester film, sheet, top tape, and metal domes, with optional EMI shielding printing. With an ultra-thin total thickness of 0.35 mm or less, it is ideal for lightweight and slim product designs.

With excellent design flexibility, tactile feedback, and stable electrical performance, Metal Dome Sheets are widely used in door locks, digital locking systems, industrial control equipment, medical devices, and a wide range of electronic products.
