Silicone Switch Button with key webbing is conductive rubber switch, which includes conductive contact under the silicone buttons. Conductive silicone switch button includes many types, carbon pills silicone switch, conductive ink button pad, metal pills rubber switch buttons. They differ in the electrical resistance and the usage lifetime.
TPV overmolding double molded rubber keyboard are rubber keypad molded by injection molding of TPV materials.
TPV called as thermoplastic vulcanizate, is mainly composed of two parts, one is plastic as a continuous phase, and the other is rubber as a dispersed phase. Usually rubber needs to be matched with softening oil or plasticizer. Vulcanizing agents and some auxiliary agents are also essential.
Silicone Rubber Keyboard is processed by compression molding used silicone raw material. Produce silicone rubber keyboard need a lot of processed: mix material and color, compression molding, conductive process: carbon pills, conductive ink printing, metal pills, nickel pills;surface symbols: laser
Metal Dome made of stainless steel, is an important part of the switch. With the conduction of the metal dome, it plays a high-quality switch between the operator and the product. At the same time, the use of the stable resilience of the metal dome (automatic return after pressing), and the long life, provide the operator with high-quality tactile feedback. The metal dome is mainly used in a membrane switch with printed circuit board and silicone rubber keyboard.
