Abstract

Un interruptor eléctrico dispuesto en una cavidad de un mandril; y un montaje de fuelle engranado de manera operable con el interruptor eléctrico, el montaje de fuelle en comunicación fluida con un fluido que rodea el mandril, de manera que una presión en el fluido que no sea menor que una presión predeterminada causa que el fuelle active el interruptor eléctrico, y una presión en el fluido menor que la presión predeterminada causa que el fuelle desactive el interruptor eléctrico.
