Abstract: An elevator car operating panel includes a plurality of push buttons corresponding to floors of a building, wherein the push buttons act on a touch screen to register elevator calls. The push buttons are mounted on an outer surface of the touch screen at locations corresponding to sensors behind the touch screen. A method to modernize and/or update a touch screen elevator car operating panel includes mounting at least one push button on a touch screen to act on the touch screen to register elevator calls.

Abstract: An elevator car operating panel has push buttons corresponding to floors of a building, wherein the push buttons act on switch contacts registering elevator calls, and wherein the push buttons are mounted on the switch contacts.

Abstract: An elevator car operating panel for registering elevator calls has a plurality of touch sensitive buttons freely configurable to correspond to floors of a building according to a specified configuration. The buttons are configured to be lighted with light of a first color when active in the specified configuration so as to be visible, and are configured to not be lighted when inactive in the specified configuration so as to be invisible.

Abstract: A control apparatus for an elevator installation has actuating elements on a front surface. The control apparatus includes an insert in the form of a key-operated switch cylinder which has a recess or a key slot. The insert is mounted in a side surface that is one of a lateral side wall of a housing, an end surface of an elevator car handrail and a side surface of a column. The recess opens transversely to the front surface. A separate auxiliary actuating element is received into the recess in the direction of an axis extending parallel to the front surface. The insert is mechanically actuatable by rotation of the auxiliary actuating element about the axis in order to trigger specific functions in conjunction with the control of the elevator installation.

Abstract: A call transmitter for the input of control commands, in particular for an elevator installation, has at least one carrier element that can be selectively received in an opening in either end face of a call transmitter housing. The housing has an inner positioning element preventing movement of the carrier element between the openings. The housing can be installed in an aperture in a front plate such that either the first end face and the carrier element are flush with the outer surface of the front plate, or a radially outwardly extending flange at the second end face abuts the outer surface with the flange and the carrier element projecting.

Abstract: This keypad for the input of control commands comprises a membrane keypad, a carrier, a keypad base and a key module. The switching operation, initiated by keys, takes place in a closed unit in the form of a carrier which encloses the keypad base and the membrane keypad. The switching contacts are located within the membrane keypad which is sealed against moisture, whereby the actual performance of the switching command take place within the sealed membrane keypad, switching plungers of the keypad base having only an actuating function. The sealed unit in the form of the carrier considerably eases installation in that the keypad base and the membrane keypad can be pre-installed in the carrier at the factory the key module can be placed over them at the installation site.
