Title
(EN) PASSIVE ELECTRICAL COMPONENT FOR SAFETY SYSTEM SHUTDOWN USING GAUSS' LAW
(FR) COMPOSANT ÉLECTRIQUE PASSIF POUR L'ARRÊT D'UN SYSTÈME DE SÉCURITÉ UTILISANT UNE LOI DE GAUSS
Abstract
(EN)
An electro-technical device includes a first housing portion electrically isolated from a second housing portion with a point source being disposed within the first housing portion. A movable conductor is connected to the first portion and is responsive to an electric field generated by the point source to cause the movable conductor to contact the second housing portion to complete a circuit and send out a control signal.
(FR)
Un dispositif électrotechnique comprend une première partie de boîtier isolée électriquement d'une seconde partie de boîtier, une source ponctuelle étant disposée à l'intérieur de la première partie de boîtier. Un conducteur mobile est connecté à la première partie et réagit à un champ électrique généré par la source ponctuelle pour amener le conducteur mobile à entrer en contact avec la seconde partie de boîtier pour terminer un circuit et envoyer un signal de commande.
