Abstract

Un dispositivo interruptor que comprende: un par de contactos normalmente cerrados; un par de contactos normalmente abiertos; medios eléctricamente conductores respondientes al calor, estando uno de dichos contactos normalmente cerrados montado con movimiento que le aparta del otro de dichos contactos normalmente cerrados en respuesta al movimiento de dichos medios respondientes al calor al ser éstos caldeados por la corriente que los atraviesa, hasta una primera magnitud predeterminada; medios eléctricamente conductores portadores de contacto, en cooperación con dichos medios respondientes al calor y que llevan montado uno de dichos contactos normalmente abiertos para movimiento que lleva a cerrarse o cooperar en contacto con el otro de dichos contactos normalmente abiertos, en respuesta al movimiento de dichos contactos normalmente abiertos, en respuesta al movimiento de dichos medios respondientes al calor al ser estos últimos caldeados, por la corriente que los atraviesa, hasta otra magnitud predeterminada, poniendo así fuera de circuito, por derivación dichos medios respondientes al calor, al cerrarse dichos contactos normalmente abiertos.
