Abstract
Perfeccionamientos en interruptores de protección contra corriente de defecto con pulsador de prueba que presentan para el cierre un circuito de corriente de prueba, un pulsador de prueba con cuya ayuda se conecta una corriente de defecto simulada que hace que reaccione el disparador del interruptor para corriente de defecto, caracterizados porque como pulsador de prueba sirve un botón de presión colocado de forma suelta en el alojamiento del interruptor y que es impulsado hacia la posición de desconexión por un muelle de patas que forma al mismo tiempo con una pata una palanca de contacto para el interruptor del circuito de corriente de prueba.
