Of course, this is a minor problem that many users can overlook. But there’s very little tactile feedback with membrane keypads, increasing the risk of typos and errors. Tactile feedback is used to “tell” the operator that his or her input was registered, usually through a light vibration. Because the keys aren’t separate moving parts, membrane keypads are more resistant to dirt, moisture and other elements than traditional mechanical keypads.īut there are still some potential downsides to using a membrane keypad, including the lack of tactile feedback. When you press down on a membrane keypad, the respective key comes into contact with the underlying circuit board thus, creating an electrical circuit that tells the device which key is being pressed. While the design of a membrane keypad varies depending on the particular model, most rely on an electrical contact between the underside of the keypad and the circuits on the actual board. Membrane keypads typically feature pressure pads containing outlines and symbols printed on the surface. This is in stark contrast to traditional mechanical keypad, where each key is a separate moving part.
