Manufacturer for Fpc Switch Circuit - Membrane switch KEY – Xinhui Detail:
Three-dimensional membrane switch
Usually, the buttons on the membrane switch only use colors to express the position, shape and size of the key body. In this way, the accuracy of the operation can only be recognized by the operator’s vision. Since there is no appropriate feedback information to indicate whether the finger is pressed in the effective range of the switch to make the switch act,
As a result, the confidence in the monitoring of the whole machine and the speed of operation are affected. A kind of membrane switch that makes the switch key body slightly protrude, slightly higher than the panel to form a three-dimensional shape, is called a three-dimensional key switch. The three-dimensional key can not only accurately specify the range of the key body, improve the recognition speed, make the operator’s touch more sensitive, but also enhance the decorative effect of the product appearance. The production of the three-dimensional key must be done in the design stage of the panel Arrangement, with process holes for precise positioning during mold pressing, and the height of the three-dimensional protrusions should generally not exceed twice the thickness of the substrate. In order to beautify the appearance of the product, the protrusions of the raised membrane switch can be made in many variations, and must be arranged in the design stage of the panel, with craft holes in order to have precise positioning when the mold is pressed, and its three-dimensional convex The height of the lift should generally not exceed twice the thickness of the substrate. For the appearance of beautiful products, the protrusions of the raised membrane switch can be changed in many ways.
