Graphic Overlays For Electronic Membrane Keypad Custom

Membrane switches can be divided into tactile and non-tactile structures. Membrane keyboard non-tactile models usually have two structures: flat non-tactile models and convex keyframes (convex blind spots in some cases). The non-tactile film switch does not need to have the feel of the button, but it requires high sensitivity. Assuming that the sensitivity of the film switch panel is not high, there will be no reflection on how to press, which greatly reduces the sense of use of the product. Open when touching but cannot not short circuit when not pressing the button. Therefore, reasonable isolation points should be added on the lower circuit key body. Usually, non-tactile film keyboards do not choose silicone rubber material.
