Abstract
LA PRESENTE INVENTION CONCERNE LES COMMUTATEURS SENSIBLES AUX CHOCS ET SUSCEPTIBLES D'EN DECELER LE PASSAGE. SELON L'INVENTION, LE COMMUTATEUR RENFERME UNE ENCEINTE 41 A COMPARTIMENT 43 REMPLI D'UN GAZ AINSI QUE D'UNE MASSE LIQUIDE 47. LA TENSION DE SURFACE DU LIQUIDE EMPECHE CELUI-CI DE PENETRER DANS L'ESPACE OCCUPE PAR LE GAZ ET DE VENIR EN CONTACT SIMULTANEMENT AVEC DEUX PORTIONS DISTINCTES D'UN CIRCUIT ELECTRIQUE 49, 51 SEPAREES ENTRE ELLES. LORSQUE L'APPAREIL RECOIT UN CHOC OU LORSQU'IL SUBIT UNE ACCELERATION SUPERIEURE EN INTENSITE A UNE VALEUR BIEN DETERMINEE, LE LIQUIDE SE DEPLACE EN DIRECTION DE L'INTERSTICE SEPARANT LES DEUX CONTACTS ET REALISE UNE JONCTION ELECTRIQUE ENTRE CEUX-CI. PAR LE BIAIS D'UN CIRCUIT ELECTRIQUE EXTERIEUR 53, 55, 61, UN DISPOSITIF D'ALERTE 35 EST ACTIONNE. LE COMMUTATEUR RESTE DANS CET ETAT TANT QU'UNE FORCE NEGATIVE SUPERIEURE EN INTENSITE A LA FORME QUI A ENTRAINE SON DECLENCHEMENT N'EST PAS EXERCEE. ON DECRIT EGALEMENT UN AUTRE MODE DE REALISATION. L'APPAREIL DE LA PRESENTE INVENTION PEUT SERVIR AU CONTROLE DE TOUT OBJET SENSIBLE AUX CHOCS.
