Key planar membrane switch membrane switch on to different colors indicates the location, shape and size of the key body in the initial stages of membrane switch is more common. Three-dimensional membrane switch: membrane switch prices are usually the PCB, button membrane switch on just using color to express the position, 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 operation, thereby affecting the confidence of the whole monitoring and 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 scope given key body PCB board membrane switch production, increasing the visibility speed, so that the operator is sensitive to touch, but also enhance the appearance of the decorative effect. Stereoscopic key production, must be designed in a panel stage should make arrangements, with technological holes, in order to have an accurate positioning in the mold pressed, the three-dimensional projections generally not more than twice the height of the substrate thickness. rigid membrane switch is the switch is to produce graphics and line on common printed circuit CCL. Characterized by a rigid membrane switch sheet drawn text will 2013PCB membrane switch, 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 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.
