Membrane switches constitute an integrated operating system combining key functions, indicator elements, and instrument panels. They comprise four components: the front panel, upper circuit, isolation layer, and lower circuit. Upon pressing the membrane switch, the upper circuit's contact point deforms downward, making contact with the lower circuit's electrode plate to complete the circuit. When the finger is released, the upper circuit contact point springs back, breaking the circuit and triggering a signal. Membrane switches feature a compact structure, aesthetically pleasing design, and excellent sealing properties. They offer moisture resistance and extended service life. These switches find widespread application across electronic communications, electronic measurement instruments, industrial control systems, medical equipment, the automotive industry, smart toys, and household appliances.
Hongmao specialises in customising various membrane switch panels, including dome switch keypads, FPC membrane switches, and circuit-integrated membrane switches.
In consumer electronics such as mobile phones and remote controls, membrane key switches offer excellent tactile feedback and an aesthetically pleasing appearance, enhancing the user experience. Within industrial control equipment, these switches provide waterproof and dustproof protection, ensuring stable operation in demanding environments. Medical devices frequently utilise membrane key switches for their responsive operation, hygienic properties, and ease of cleaning, meeting the stringent requirements of the healthcare sector.
Digital membrane switches possess waterproof, dustproof, and oil-resistant capabilities. Their sealed design effectively shields against liquids, dust, and chemical agents, making them suitable for demanding environments such as kitchen appliances, outdoor equipment, and medical instruments. Featuring metal spring or rocker-switch dual-contact designs, they withstand millions of press cycles while offering corrosion resistance and high-temperature tolerance, ideal for high-frequency operation scenarios. With controllable thickness and lightweight construction, they can be integrated into both flat and curved surfaces, optimising internal space and aligning with the trend towards slimline modern electronics. Support for pattern screen printing enables customised designs, making them widely applicable in smartwatches, industrial instruments, and other devices with high aesthetic demands.
