Abstract (en)
A device for detecting the opening or closure of a door or window of a building or vehicle is described, for example for the purpose of activating or disactivating an illumination device or an alarm; this detector device includes a continuous perimitral seal against which the said door or window can cooperate by contact under predetermined pressure in a closure position, and means for detecting the compression state of the seal comprising means for detecting the electrical resistance of at least a predetermined section of the said seal, at least the said predetermined section being made of an electrically conductive elastomeric material the electrical resistance of which varies as a function of the compression state to which it is subjected. <IMAGE>
