Abstract: A selection device for shifting a vehicle transmission, with a operating element (4), which can be rotated into different shift positions (6, 7, 8, 9) about an axis of rotation (5) and with a shaft (21), which is connected to the operating element (4) and is rotatable about the axis of rotation. An angle of rotation sensing device (32) is connected to the shaft, by which a rotation of the operating element (4) about the axis of rotation (5) can be sensed. An actuator (22) is provided by which a torque can be applied to the shaft (21) or a torque can be applied to oppose a rotation of the shaft (21). A control is connected to the angle of rotation sensing device (32) and to the actuator (22) for controlling the torque.

Abstract: A switch cupboard (1) comprises a case (2), several modules (30 and a supporting rail (4), the modules (3) being secured on the supporting rail (4). The disclosed switch cupboard (1) is characterized in that it is designed in functional blocks and modules, so that all modules (3) required by a machine and only those modules are mounted in the switch cupboard case (2).

Abstract: An input/output module (1) with a terminal unit (2) for connection of sensors or actuators with an electronic unit (3) and with a bus connection element (4). The terminal unit (2) has at least one input/output (5) located in a surface thereof and the terminal unit is connected by the electronic unit (3) to the bus connection element (4). To replace the electronic unit (3), the terminal unit (2) can be removed from the electronic unit (3) without the need to remove lines (6) connected to the inputs/outputs (5). The terminal unit (2) is able to be mounted to the electronic unit (3) in each of two positions, the input/output (5) in the two positions lying in planes that are offset relative to each other by 90.degree..
