Abstract
La presente invención se refiere a un interruptor de proximidad para usarse con una fuente de suministro o abastecimiento de corriente alterna a fin de controlar una carga conectada en serie con el interruptor, que consiste de: un circuito de suministro o abastecimeinto de energía de bajo voltaje que incluye un capacitor de almacenamiento y un Diodo Zener; un medio detector para generar una señal de salida en presencia de un objeto de referencia detectado conectado al circuito de suministro de energía de bajo voltaje; un elemento de conmutación controlable y conectado, durante el uso a través de la fuente de suministro de corriente alterna y que tiene una entrada de control conectada a la señal de salida del detector; la fuente de suministro de energía de bajo voltaje incluye un medio para limitar una corriente que carga al capacitor de almacenamiento hasta un valor máximo predeterminado, cuando el interruptor está "desconectado", caracterizado en que el medio limitador de corriente incluye un dispositivo de resistencia variable conectado en serie con el capacitor de almacenamiento, y un medio que responde al nivel de la corriente de carga para controlar la resistencia del dispositivo.
