Double-layer structure remote control with metal dome array is created by adding a layer of LGF to the existing standard dual-layer structure or EMI structure of conductive film, thereby achieving excellent light distribution. The working principle of LGF light-guiding film/sheet utilizes the principles of light reflection and refraction, combined with specialized optical software design, to perform microstructural processing on the optical fiber film, thereby transforming a “point light source” into a “surface light source.” Light beams are emitted from the medium at appropriate angles and densities, achieving an optimal effect of uniform light emission. The design of LGF conductive film/light guide plate can reduce the number of LED lights required, addressing issues such as uneven brightness distribution, high power consumption, large space occupancy, and high costs.

Metal Dome Array Uses
Consumer Electronics: Metal dome arrays are extensively used in consumer electronics such as smartphones, tablets, remote controls, gaming devices and wearable technology.
Automotive: Metal dome arrays are found in automotive applications including dashboard controls, infotainment systems, steering wheel controls and keyless entry systems.
Medical Devices: In medical devices such as patient monitoring systems, diagnostic equipment and handheld devices, metal dome arrays are used to provide tactile feedback for user-input interfaces. Their precise actuation and long-term reliability are critical in the medical field.
Industrial Control Systems: Metal dome arrays are employed in industrial control panels, machinery interfaces and equipment controls.
Appliances: Metal dome arrays are used in household appliances including microwave ovens, washing machines, dishwashers and coffee makers. They ensure responsive and reliable operation of control panels and user interfaces.
Industrial Equipment: Metal dome arrays are employed in various industrial equipment such as manufacturing machinery, process control systems, and test and measurement devices. Their tactile feedback facilitates user interaction and control.
Custom Metal Dome Array
Dome array assemblies have become standard practice for numerous membrane switch/circuit manufacturers, who utilise this technology to effectively reduce costs and accelerate assembly speeds. Operators need only install a single large dome array in one application, rather than fitting individual domes one by one, thereby substantially shortening production cycles. This technology also minimises installation errors and the occurrence of ‘double domes’, significantly enhancing product quality and delivering multiple benefits.
Dome arrays also markedly enhance tactile feedback in rubber keypads or, when directly affixed to circuit boards and overlaid, achieve a tactile switch effect.
Our product line encompasses diverse dome array designs, ranging from basic single-layer PET domes to complex structures requiring spacer layers and electromagnetic shielding, all available for customisation.
