An apparatus for actuating a slidable and pivotally movable cover for use with an automobile roof opening comprises a control element, e.g. a disc, driven by an electric motor. A plurality of switch cones are preferably secured at equal radial distances from the rotational axis of the control disc. An actuating plunger is radially displaceable by each cam to move a biased actuating element which then operates a switching member of a control switch. This switches off the motor when specific portions of the cover are reached. In a first position of the actuating element, in which it is held against its bias by energized electromagnetic means, the actuating element is operable to displace the switch pin to switch off the motor. In a biased second position of the actuating element, with the electromagnetic means de-energized in consequence of the motor being switched off, the actuating element holds the switching member in its displaced position until the energizing circuit is again energized. |
