Abstract

Interruptor eléctrico, en especial, microinterruptor, con por lo menos un resorte (4, 17) de contacto transferible mediante un órgano de accionamiento a diversas posiciones de conmutación, cuyo resorte se ha dispuesto en una montura configurada como contacto eléctrico y el cual presenta una armadura (5) elástica cerrada, donde en la armadura (5) elástica se han dispuesto dos lengüetas (6, 7, 18) elásticas flexibles elásticamente que se extienden en aproximadamente direcciones antagónicas, donde una primera lengüeta (6) elástica se ha configurado como recuperadora para el órgano (3) de accionamiento y una segunda lengüeta (7) elástica se ha configurado como elemento inversor para la zona (9) de contacto del resorte (4, 17) de contacto y donde las lengüetas (6, 7, 18) elásticas presentan zonas de agarre en zonas superficiales mutuamente opuestas de la montura (8), caracterizado por que la primera lengüeta (6) elástica realizada como elemento recuperador es una hoja de ballesta con pandeo, cargada elásticamente por lo menos longitudinalmente con tensión de compresión y por que cada lengüeta (6, 7, 18) elástica presenta en la zona de su articulación en la armadura (5) elástica un estrechamiento de sección transversal decreciente.Electric switch, in particular, microswitch, with at least one contact spring (4, 17) transferable by means of an actuator to various switching positions, whose spring is arranged in a mount configured as an electrical contact and which has a closed elastic reinforcement (5), where in the elastic reinforcement (5) two elastically flexible elastic tabs (6, 7, 18) have been arranged that extend in approximately antagonistic directions, where a first elastic tongue (6) has been configured as recuperator for the actuator (3) and a second elastic tongue (7) has been configured as an inverter for the contact area (9) of the contact spring (4, 17) and where the tabs (6, 7, 18 ) elastic have grip areas in mutually opposite surface areas of the mount (8), characterized in that the first elastic tongue (6) made as a recovery element is a sheet of crossbow with buckling, elastically loaded at least longitudinally with compression tension and because each elastic tongue (6, 7, 18) has a narrowing cross-sectional narrowing in the area of its joint in the armature (5).
