The present invention relates to a switching device having programmable functionality markings. The switching device has: a switch, a functionality marking programmer, a functionality marking display, and a control module. The switch is used to control power supply to an electrical appliance. The functionality marking programmer allows a user to designate the switch to a specific functionality with a corresponding functionality marking. The functionality marking display displays the functionality marking programmed by the functionality marking programmer. The control module includes a processor and a memory. The memory stores computer executable instructions. When executed at the processor, the computer executable instructions is configured to: receive functionality marking programming instructions from the user via the functionality marking programmer, designate the functionality of at least one switch with a functionality marking according to the functionality marking programming instructions received, and display the programmed functionality marking of the switch via the functionality marking display.

A device for inputting commands includes a casing, a rotatable disk, and a processor. The rotatable disk can rotate relative to the casing, and has a plurality of input modes. The rotatable disk includes a switch button for switching among the input modes. The rotatable disk further includes a pointer. The casing includes an annular area surrounding the rotatable disk. The annular area has a plurality of input positions. The input positions correspond to characters of one character set corresponding to the current input mode. The processor is received in the casing, and can generate a command or control signal according to a character corresponding to an input position when the pointer is aligned with the input position.

A position indicator for a tap changer of a tapped transformer comprises a display device (51) for displaying the current switch position of the tap changer, which display device (51) is stepped with each switchover and which comprises first and second display disks (21, 26); an indicator gear (10) that is coupled to the two display disks (21, 26) for driving them in a switch-direction-dependent manner and which can be coupled to a switching shaft of the tap changer; wherein each display disk (21, 26) comprises sets of numbers in an angularly extending or circular row; with each step one number of the row of numbers on the first display disk (21) and one number of the row of numbers on the second display disk (26) are positioned side by side such that these numbers represent the current switch position of the tap changer expressed as digits combined to form a multi-digit number.

A rotary/push operating device (10) for a man-machine interface, in particular for an operating unit of a vehicle, comprises a manually operable rotary/push element (12) which can be rotated about a rotational axis (15) and which can be pushed down in the direction of the rotational axis (15), and a rolling-body bearing (14) which defines the rotational axis (15) and which comprises a immobile bearing ring (18), a movable bearing ring (20), and a rolling-body cage (22) arranged between said bearing rings. The rotary/push element (12) is coupled to the movable bearing ring (20) in such a manner that the rotary/push element (12) will move together with the movable bearing ring (20) when, during rotation of the rotary/push element (12), the movable bearing ring (20) rotates or is axially moved in the direction of the rotational axis (15). The rolling-body cage (22) comprises a plurality of rolling bodies (24) arranged in at least one radial plane of the rolling-body cage (22). The immobile bearing ring (18) and the movable bearing ring (20) form at least one circular moving channel (27,28) in which the rolling bodies (24), during rotation of the rotary/push element (12) in the circumferential direction of the two bearing rings (18,20), are movable with rolling movements on opposite moving tracks (29,30,31,32) of the two bearing rings (18,20), and, when the rotary/push element (12) is being pushed down in the direction of the rotational axis (15), can move on the moving tracks (29,30,31,32) at a right angle relative to said circumferential direction. For limiting the movement of the rotary/push element (12) in the direction of the rotational axis (15) between a base position and a push-down position, the rotary/push operating device (10) further comprises end abutment elements (45).
