Shenzhen Boer Zhuo Electronic Technology Co. (http://www.boerzuo.com) is located in Shenzhen, Guangdong Province, China Guihua Road, Guanlan Town, District No. 223, Contact: Chen Ting membrane switch is a key function, indicating element, Instrument panel as one of an operating system. By the panel, the circuit isolation layer, the circuit composed of four parts. Turned to touch-type normally open switch, membrane switch under normal circumstances, the upper and lower contacts were disconnected. Press the membrane switch, the contacts on the circuit downward deformation of the plate in contact with the circuit conduction, release your finger, the upper circuit contact bounce back, the circuit is disconnected, loop trigger a signal. Structured 2013FPC membrane switch membrane switch, beautiful appearance, good seal. With anti-moisture, long life and other characteristics. Widely used in electronic communications, electronic measuring instruments, industrial control, medical equipment, automotive, smart toys, household appliances and other fields. FPC film opened on different places ordinary membrane switch circuit is no longer just a silver printed circuit FPC membrane switch production, but the performance is more stable FPC circuit material instead, more heat and corrosion resistance. Shenzhen Electronic Technology aka Film Treasures membrane switch, established in 2005, has achieved ISO9001 and ISO14001 certification Our company is a professional design and produce membrane switches and touch panels of high-tech industries. Our main production of membrane switch with an LED membrane switch, FPC membrane switch, PCB board membrane switch, EL membrane switch, touch switches and aluminum thin-film membrane switches and silicone membrane switch.
