Abstract
A system is disclosed for energizing an electric motor for forward or reverse rotation, which motor operative to open or close a side window pane of a door or a sun roof panel of an automobile. The motor is energized for forward or reverse rotation in accordance with the status of a pressure sensitive switch which is mounted on a window frame to detect the presence of an object or hand and an operation of up/down command changeover switches. If the presence of an object is detected by the sensor during the forward rotation of the motor which is effective to close the window pane, a self-hold circuit is triggered or set, and the motor is energized for reverse rotation. The motor is deenergized at a given time interval after the sensor has ceased to detect the object. The motor remains at rest as long as the self-hold circuit is set. In certain embodiments, the self-hold circuit is reset when up command changeover switch is moved from its up position to its non-operative position. In other embodiments, the self-hold circuit is reset when down command changeover switch is transferred to its down command position.
