Keypad for telephone stations

摘要

Keypad with a plurality of key buttons (2) disposed in a housing (1) which act, via lifting bellows (4) of a rubber mat (5) on a contact foil (6). In a keypad of this type, electromagnetic interference is intended to be prevented during dialling operation by simple means. To this end, a metal pressure plate (7) is disposed on the side of the contact foil (6) which faces away from the key buttons (2). This ensures not only that the keypad is screened from electromagnetic interference but also that the key forces are effectively absorbed. <IMAGE>
