Key planar membrane switch membrane switch on to a different color indicates the position of the key body, the shape and size of the latest PCB board membrane switch, membrane switch in the initial stage 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 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 PCB panel membrane switch production, constitute the three-dimensional shape of the membrane switch, called a three-dimensional key switch. Dimensional key not only to accurately scope given to the key body to improve identify speed, so that the operator is sensitive to touch, but also enhance the appearance of the decorative effect. Stereoscopic key making, should be ready at the design stage panel arrangements with technological holes, in order to have an accurate positioning of PCB board membrane switch wholesale repression in the mold, the three-dimensional projections generally not more than twice the height of the substrate thickness.
