Factory Customized Flat Membrane Switch, Control Panel Overlay Printing Rubber Keypad
Membrane switches are everywhere, just look around, but how many people truly pay attention to the circuit design? Typically, HMI engineers and designers focus on the visible design elements first, such as overlays, pantone colors, and backlighting. Next, the focus is usually on the keypad design, such as the switching mechanism, keypad material, and tactile response. Unfortunately, all too often, designers and engineers fail to provide sufficient attention to one of the most critical design features of a membrane switch, the flexible circuit behind the overlay.
