Abstract: An auxiliary input device is provided for an electronic device including a capacitive touch sensor. The auxiliary input device includes at least one key, which includes an upper conductive layer, a lower conductive layer, and at least one supporting element. The lower surface of the lower conductive layer has a specific pattern. The supporting element is disposed between the two conductive layers such that there is a distance maintained between the two conductive layers.
