A motion sensing element with position sensing includes a case, a magnet positioned within the case, a spring assembly having an electrically conductive member and a coil assembly coupled to the spring assembly. The coil assembly and magnet are moveable with respect to one another. A capacitor plate is proximate the electrically conductive member with a distance between the capacitor plate and electrically conductive member being variable as the magnet and coil assembly move. Leads connect the capacitor plate and electrically conductive member to a sensing circuit for estimating the relative positions of the magnet and coil assembly.
L'invention concerne un élément de détection de mouvement avec détection de position, cet élément comprenant un boîtier, un ensemble ressort comportant un élément électroconducteur et un ensemble enroulement couplé à l'ensemble ressort. L'ensemble enroulement et un aimant peuvent se déplacer l'un par rapport à l'autre. Une plaque de condensateur se trouve à proximité de l'élément électroconducteur, la distance entre la plaque de condensateur et l'élément électroconducteur étant variable lorsque l'aimant et l'ensemble enroulement se déplacent. Des broches de connexion raccordent la plaque de condensateur et l'élément électroconducteur à un circuit de détection afin d'évaluer les positions relatives de l'aimant et de l'ensemble enroulement.
