This keypad for the input of control commands consists in essence of a membrane keypad (1), a carrier (5), a keypad base (10) and a key module (16). The switching operation to be initiated by keys (30) takes place in a closed unit in the form of a carrier (5) which encloses the keypad base (10) and the membrane keypad (1), the switching contacts being located within the membrane keypad (1) which is sealed against moisture and, more specifically, the registration of the command taking place within the sealed membrane keypad, the switching plungers (11) of the keypad base (10) having only an actuating function. The sealed unit in the form of the carrier (5) considerably eases installation in that the keypad base (10) and the membrane keypad (1) can already be preinstalled in the carrier (5) at the factory and the key module (16) can be placed over them.
