Membrane key switches comprise a panel, upper circuit, insulating layer, and lower circuit. Upon pressing the key, the upper circuit contact engages with the lower circuit contact to establish electrical conduction, thereby completing the circuit and generating an electrical signal. When the key is released, the contacts separate, breaking the circuit. Its operation is precise and responsive, akin to a finely-tuned mechanism, ensuring each operation accurately transmits electrical signals.
There exists a type of flat membrane key switch whose surface is smooth and even, imparting a sense of clean aesthetics. It is frequently employed in electronic devices where appearance is paramount. Alternatively, a raised membrane key switch features distinctly elevated key areas, facilitating blind operation for users. Furthermore, tactile membrane key switches employ optimised elastomer design to deliver pronounced key feedback, thereby enhancing the operational experience.
Membrane key switches offer excellent tactile feedback and an aesthetically pleasing appearance on consumer electronics such as mobile phones and remote controls, enhancing the user experience. Within industrial control equipment, these switches provide waterproof and dustproof protection, ensuring stable operation in demanding environments. They are also widely used in medical devices, where their responsive operation and hygienic, easy-to-clean properties meet the stringent requirements of the healthcare sector.
Hongmao customises various membrane switch panels, dome switch keypads, FPC membrane switches, and circuit membrane switches.
Surface Texture: The frosted finish imparts a refined matt effect to the keys, offering a soft, non-slip tactile experience ideal for applications requiring accidental touch prevention, such as medical equipment.
Durability: Constructed from PC/PET material, it withstands temperatures from -20°C to +70°C, features waterproof and dustproof properties (IP65 rating), and boasts a lifespan exceeding 5 million cycles, making it suitable for high-frequency use in medical instruments and similar devices.
Sealed Construction: The fully sealed design effectively isolates dust, grease, and harmful gases, safeguarding internal components.
Installation Convenience: Supports adhesive backing for straightforward mounting, streamlining equipment assembly and reducing associated costs.
