PCT No. PCT/DE90/00001 Sec. 371 Date Aug. 30, 1990 Sec. 102(e) Date Aug. 30, 1990 PCT Filed Jan. 3, 1990 PCT Pub. No. WO90/07437 PCT Pub. Date Jul. 12, 1990.A rain-actuated control for covering systems makes it possible to obtain a device capable of automatically closing open coverings in the event of rain. The device must be simple and easy to mount in existing installations. The rain-actuated control comprises a sensor consisting of two electrodes (1,15) with an intermediate layer of glass (13) and air (29) which functions as a capacitor. When rain is deposited (30) on the glass, the dielectric constant of the glass is changed, and signals are generated, which cause the control system to close the covering system. Automobile windows and automobile bodies can be used advantageously as elements of the capacitor.
