Abstract
A control device designed to detect the open or closed state of a door or window of a building or vehicle, for example in order to activate/deactivate an illumination or alarm device, is described; this control device includes a continuous perimetral seal with which said door/window is designed to co-operate, making contact with a predefined pressure in a closed position, and means for detecting the compressive state of the seal, consisting in means for detecting the electrical resistance of at least one predefined section of said seal, at least said predefined section being made of an electrically conducting elastomer material designed to vary its electrical resistance depending on the state of compression to which it is subject.
