Abstract

Circuito activador de solenoide que incluye un primer y un segundo transistores de salida conectados al solenoide y que proporcionan unas trayectorias paralelas de corriente para aquél de resistencias relativamente elevada y baja, respectivamente, medios conectados a un terminal de entrada para permitir la conducción de uno u otro transistor cuando la señal presente en el terminal de entrada se encuentra en un primer estado e impedir la conducción de ambos transistores cuando aquella señal se halla en un segundo estado, y medios detectores de la corriente del solenoide que controlan al segundo transistor citado, de manera que ésta conduzca cuando la señal presente en el terminal de entrada se encuentra en el primer estado mencionado, hasta que la corriente del solenoide se eleve por encima de un nivel predeterminado.
