One might say that a ruler, being such a commonplace item in daily life, is hardly remarkable. Surely anyone in their right mind should know how to use one. Yet I've discovered that in the manufacturing process of membrane switches, more than just a ruler is required.
LGF light-guiding film/sheet achieves superior light distribution by incorporating an LGF layer onto conventional dual-layer or EMI-structured conductive films. Its operating principle leverages the principles of light reflection and refraction, combined with specialised optical software design, to apply microstructural processing onto the fibre-optic film.
A membrane switch key that remains depressed and fails to spring back is also known as a dead key phenomenon, which is fatal for the membrane switch; it directly causes the entire product to malfunction. So why does the dead key phenomenon occur? Let us briefly analyse the causes below:
The service life of membrane switches typically exceeds one million cycles, which is significantly higher than the average lifespan of 200,000 cycles for standard silicone rubber switches. This is primarily because membrane switches operate through electrical contacts, meaning their longevity is intrinsically linked to the durability of these contacts. Generally, as long as the electrical contacts remain intact,
