Abstract: A data input and/or operator control system, particularly a keypad, also a POS keypad, having a lower portion and an upper portion and also at least one printed circuit board and at least one retaining plate. Inside, one or more protective mat(s) made of an elastic material is/are preferably adhesively bonded to the printed circuit board. In this protective mat, the components of the printed circuit board are recessed to as small an extent as possible and air ducts are incorporated in order to ensure that the keys are ventilated in relation to one another.
Abstract: A data entry and/or operating system, particularly a keyboard, also a POS keyboard, includes a lower part and an upper part as well as at least one circuit board and at least one retainer plate, the retainer plate lying on the lower part. One or more bushings are integrated for the purpose of connecting the circuit board to the retainer plate. The upper part is formed from a rubber mat having keys, and the stability of the keyboard is assured by the circuit board, bushing and metal retainer sheet. The lower part is connected to the upper part in a sealed manner.
