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.

A data input and/or operating system, comprising
- a lower part made of silicone;
- an upper part made of silicone;
- at least one printed circuit board;
- and
- at least one retainer plate,
- wherein one or more protective mats of an elastic material are adhesively bonded in the interior to the printed circuit board,
- wherein components of the printed circuit board are recessed in the protective mat and air channels are integrated to assure ventilation of keys relative to one another, and
- wherein the retainer plate lies on the lower part, wherein one or more bushings are integrated for connecting the printed circuit board with the retainer plate, where the upper part is formed by a silicone mat with keys, wherein the stability of the keyboard is realized by the printed circuit board, the bushings, and the retainer plate, and wherein the lower part is connected sealingly to the upper part.
A data input and/or operating system, comprising
- a lower part made of silicone;
- an upper part made of silicone;
- at least one printed circuit board;
- and
- at least one retainer plate,
- wherein one or more protective mats of an elastic material are adhesively bonded in the interior to the printed circuit board,
- wherein components of the printed circuit board are recessed in the protective mat and air channels are integrated to assure ventilation of keys relative to one another,
- wherein an intermediate mat, made of silicone, which seals all spaces between the protective mat and the retainer plate, is placed on the protective mats, and
- wherein the intermediate mat has at least one rib, which lies circumferentially against the bushing.
A data input and/or operating system, comprising
- a lower part made of silicone;
- an upper part made of silicone;
- at least one printed circuit board;
- and
- at least one retainer plate,
- wherein one or more protective mats of an elastic material are adhesively bonded in the interior to the printed circuit board,
- wherein components of the printed circuit board are recessed in the protective mat and air channels are integrated to assure ventilation of keys relative to one another, and
- wherein the retainer plate has bent edges that extend upwards toward the upper part.
