Our product is a metal dome switch array consisting of white transparent PET dome carriers backed with pressure-sensitive adhesive, enhanced with black PET domes and featuring a double-layer structure air channel venting layer.We customize dome arrays according to your preferences, including the style and quantity of domes you prefer, cut to your specific size and shape requirements. Additionally, we offer the flexibility to incorporate different sizes, shapes, and forces of metal domes within the same array.
Overall, metal dome switches with black dot PET significantly improve height, durability, sensitivity, and user experience. They are widely used in remote control buttons with printed embossed or domed designs, as well as in electronic products such as bank Ukeys and intelligent repeating devices.
1. Increased switch height: The black dot PET raises the height of the metal dome switch, improving the device's feel and comfort.
2. Precise positioning: The black dot PET is used for precise positioning of the metal dome on the overlay, ensuring stability and accuracy during button presses.
3. Enhanced sensitivity: The black dot PET increases the sensitivity and responsiveness of the button, making operation smoother and faster.
4. Increased durability: The black dot material typically has high wear resistance, extending the lifespan of the button.
5. Improved tactile feel: The use of black dot PET improves the tactile feel of the button, making it more comfortable and providing a better user experience.
6. Anti-slip design: The black dot helps prevent the button from slipping, enhancing the reliability and stability of the operation.

The double-layer PET dome switches are widely utilized in electronic products and mechanical devices, including but not limited to smartphones, tablets, remote controls, automotive keypads, medical equipment, smart home devices, digital cameras, gaming controllers, appliance control panels, industrial control panels, and consumer electronics.
The double-layer PETMetal Dome Array differs from single-layer conductive film in that it includes an additional Spacer layer, allowing the dome to adhere better to the Mylar and maintain good contact with the circuit board, resulting in improved tactile feedback (similar to the "dome" effect in membrane switches). Additionally, the ventilation holes on the double-layer conductive film more effectively prevent the PET layer from being scratched by the sharp edges of the dome and prevent dust from entering the PET layer.
15-key, nickel-plated dome switches, waist-shaped 5mm Metal Dome Array with white PET spacer.
The double-layer structured 15-key Metal Dome Array with a white PET adhesive spacer differs from a single-layer conductive film by incorporating an additional Spacer layer. This allows the domes to adhere better to the Mylar and maintain optimal contact with the circuit board, resulting in enhanced tactile feedback (reminiscent of the "dome" effect in membrane switches). Furthermore, the ventilation holes on the double-layer conductive film more effectively prevent the PET layer from being scratched by the sharp edges of the domes and deter dust from entering the PET layer. The PET spacer primarily serves to improve the structural conductivity height, thereby enhancing the tactile performance of the keys and providing a comfortable pressing experience during key actuation.
