PCB board membrane switch, PCB board membrane switch production, Shenzhen PCB board provided by the Endowment membrane switch membrane switch. Shenzhen Boer Zhuo Electronic Technology Co., Ltd. (www.boerzuo.com) Shenzhen, Guangdong Business League certification of quality companies, with TCL Corporation, goods Electric, KPT electronics, and other brands, has a good reputation, honesty, service First, click on the "Business League call" icon on the page, we will be happy to serve you! Membrane switch is a key function indicating element, one of the instrument panel as an operating system. The panel, circuit, an isolation layer composed of the four parts of the circuit. Touch the normally open switch is turned on the PCB type of membrane switch, the switch under normal circumstances the film, the contact OFF state. After pressing the membrane switch, the contacts on the circuit deformed downward into contact with the plate under the conduction circuit, release your finger, the circuit contacts bounce back off the circuit board PCB membrane switch prices, triggering a signal circuit. Membrane switch rigorous structure, beautiful appearance, good sealing. 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 membrane switch membrane switch different from ordinary places the circuit is no longer just a silver printed circuit, but the performance is more stable FPC circuit materials instead of better high temperature, corrosion. Rigid membrane switch is the switch and line graphics are produced on a common printed circuit CCL. Characterized by a rigid membrane switch has drawn text, process stability, low resistance, and some components soldered directly to the back of the circuit. In the case of the small size of the PCB membrane switch production, eliminating the need for a hard liner layer. Rigid metal membrane switch is generally used as a guide through the maze guide contacts, so a better feel. The downside is less flexible in the machine installed with associated membrane switch easy, plug-and often require soldering wire leads through the flat cable. Feedback rigid membrane switch in addition to the beep signal, LED indication, the general feeling can be metal shrapnel. FPC flexible printed circuit is a highly reliable, excellent flexible printed circuit polyimide or polyester film to the substrate made of.
