Shenzhen Boer Zhuo Electronic Technology Co., Ltd. (http://www.boerzuo.com) Shenzhen, Guangdong 20 20 ShangMeng quality certified company, with TCL Corporation, goods Electric, KPT electronics, and other brands, has a good reputation , honesty, service-oriented "business alliance Service" icon on the page, we will be happy to serve you! 20 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 small size, can save hard liner layer. Rigid metal membrane switch is generally used as a guide through the maze guide contacts, so a better feel. The downside 20FPC membrane switch, 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 membrane switch above the loading plate and welding can also be LED, ordinary silver line films are used to print 20FPC membrane switch price, but FPC membrane switch resistance and performance are relatively stable compared to the normal membrane switch, more High temperature corrosion. Button 20 on the membrane switch to a different color indicates the location, shape and size of the key body in the initial stage of the membrane switch is more common. Dimensional membrane switch: Usually, only the key switch on the film to express the position of use of color, shape and size of the key body. In this way, only with the operator's vision to identify the accuracy of the operation, because there is no proper feedback to indicate whether a finger on the switch so that the effective range of the switching action 20FPC membrane switch companies, thereby affecting the confidence of the whole monitoring and the speed of operation. A key to open the body to make slightly raised, slightly higher than the panel, constitute the three-dimensional shape of the membrane switch, called a three-dimensional key switch. Dimensional key not only to accurately given key range body, increasing the visibility speed, so that the operator is sensitive to touch, not the case in the area, eliminating the need for a hard liner layer. Rigid membrane switch is generally used as a conducting metal guide 20 contacts maze FPC membrane switch factory in Shenzhen, the 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. 20
