The invention relates to two switching devices and a process for external force-actuated driving devices in a motor vehicle, especially windows and sliding roofs. According to the invention, depending on the dynamics and/or degree of displacement of an actuating component (1, 101, 201, 301, 401, 501), control signals are generated which code the displacement speed and travel, the position, the displacement duration and/or direction of the item to be displaced. The actuating component is in particular an unrestrictedly rotatable component (1, 101, 201, 501) which, during its rotation, generates control signals for an electronic control unit (4, 104). The invention provides two switching devices and a process giving the user the greatest possible control over the displacement of the component concerned.
