Abstract
A control lever (10) is provided with a grip (12), which in a joint (14) having two degrees of freedom is supported in a housing (11) and can be switched from an initial position in various directions for activating shift elements (18, 19), whereby spring elements (41, 42) are provided for returning the grip (12) to its initial position, and with a functional device for overcoming a pressure point during the activation and/or for retaining a desired shift position. In order to provide functional devices in greater numbers in a gearshift lever of this type without requiring substantially more installation space or substantially higher costs, provision is made that the functional device is constituted by an electrically controllable hydraulic arrangement (35), which connects to diametrically opposing shift elements (18, 19), which can be activated by the grip (12) in two opposing directions of motion.
