Bump-type membrane switches find extensive application in small electronic devices such as remote controls, calculators, toys, household appliances, and instruments. Their excellent tactile feedback and aesthetically pleasing appearance effectively enhance the user experience and market competitiveness of products.
Tactile Feedback and Lifespan
Features a polyester dome structure with an actuation travel of 0.4–0.7mm and an actuation force of 50–150gf, delivering a tactile feel comparable to traditional mechanical keys. Mechanical lifespan exceeds 3 million cycles, making it suitable for high-frequency pressing applications (e.g., CNC machine tool panels).
Sealing and Environmental Adaptability
Features an IP67 protection rating, offering dust and water resistance alongside corrosion resistance. Operates within a temperature range of -20°C to +70°C, making it suitable for harsh industrial environments.
Structure and Manufacturing Process
Features a five-layer construction comprising a PET/PC panel layer, polyester dome layer, silver paste circuit layer, and others. Achieves high-precision manufacturing through screen printing and hot-press lamination techniques.
Additional Features
Supports backlit displays and customisation for special shapes.
