Capacitive Touch Keypad with Sound Feedback
This keypad is a USB Keypad with audio feedback. There is a piezo buzzer on the back of the keypad that makes a clicking sound every time a button is triggered. Audio is a great way to give the users feedback as they interact with a product.
This keypad has a rubber molded overlay with a 3D surface. This overlay has a negative emboss or recessed surface which makes a groove for the finger to easily follow the slider and wheel. There are positive bumps inside the slider groove to give the user a feel for each gradation. This makes it very easy to use even when you are not looking at it. The groove in the wheel helps keep your finger right on track! Also notice the speed of the capacitive touch system, you never miss a button press! We are also uniformly back lighting the logo and the icons of the 3 buttons.
