Abstract

CONMUTADOR SENSIBLE A LA ACELERACION O DECELERACION. ESTA FORMADO POR UNA BASE METALICA (10) CON DOS VARILLAS (12, 14) ROSCADAS EN UN EXTREMO Y RECLACADAS EN EL OTRO, DENTRO DE UNOS AVELLANADOS (18) DE LA BASE. EN ESTAS VARILLAS SE SUJETA UNA CUBIERTA DE PLASTICO (20) CONTRA LA BASE (10), A TRAVES DE LA CUAL SE OBSERVA EL MECANISMO CONMUTADOR (26). ESTE CONSTA DE UN PENDULO (28) Y DE DS GRUPOS DE JUEGOS DE CONTACTOS (30), CADA UNO DE LOS CUALES TIENE UNOS CONTACTOS (36) ABIERTOS Y OTROS (34) CERRADOS, CON UNAS PASTILLAS DE ENCHUFE (84) QUE PUEDEN SER PROLONGACION DE LAS DEL RESORTE. EL PENDULO, SENSIBLE A LA ACELERACION POSITIVA O NEGATIVA, ACCIONA LOS CONTACTOS MEDIANTE UNA PATILLA (126) Y UN IMPULSOR (96). DE APLICACION EN SISTEMAS DE SEGURIDAD, COMO FRENOS Y SIMILARES EN TRENES Y VEHICULOS EN GENERAL.
