1. A control circuit for the driving motor of an openable panel for a motor vehicle, such as an openable window glass or roof, of the type comprising manually actuatable switching means (2, 4) controlling, through an electronic circuit (7D, 7M), the supply of power to the motor (1) in both directions for closing or opening the panel, either in accordance with a fully automatic cycle covering the total travel of the panel, or in accordance with a manual cycle for placing the panel selectively in any intermediate position of its travel, said switching means (2) comprising, for each direction of operation of the motor (1), a first control element (6M, 6D) for the initiation of the automatic cycle, and a second control element (5M, 5D) independent of the first for the selective positioning of the panel, characterized in that there is provided, for each direction of operation of the motor, an inverting contact (8M, 8D) of an electromagnetic relay (9M, 11M; 9D, 11D) arranged in such manner as to conduct the current of the motor in its position of rest in series with said respective second control element (5M or 5D) and also so arranged as to ensure the automatic operation of the motor (1) in the operating position, the relay being then excited by said respective first control element (6M, 6D). |
