An operating arrangement for combined actuation of two movable control devices with the aid of a single operating lever has movement-translating means between an operating device with its associated operating lever and the control devices. The operating device includes a pivot plate (1) centrally mounted by a ball joint for adjustment in any desired inclination in any direction. Two pairs of Bowden operating cables (6, 11) are connected to the pivot plate in mutually right-angular planes. Each pair of cables is connected to a control device (16). In each cable pair one end of the casing (8) of a first cable (6) is connected to a fixed means (9) adjacent the pivot plate, and the wire (7) of said cable (16) is pivotably connected to the pivot plate, while the other end of the casing is connected to the control device, and the wire (7) of said cable (6) is connected to a fixed means adjacent the control device. One end of the casing (13) of the second cable (11) in the pair is connected to a fixed means adjacent the pivot plate and the wire (12) associated with said casing (13) is pivotably connected to the pivot plate while the other end of the casing is connected to a fixed means adjacent the control device and the wire (12) of the cable (11) is connected to the control device. Force transmission from the operating device (20) to the control device (16) always takes place during the development of tensional stress in the wire of the active cable. The arrangement enables the use of relatively light cables, since the wires do not transmit force by means of compression. The light cables enable smaller bending radii and reduced inner friction in the cable for a given bending radius. The light cables permit neater cable positioning to suit the structure on which the operating arrangement is used.
