Abstract
1. Dispositivo para el control del funcionamiento de bombas sumergibles, en el que unos medios de flotación intervienen sobre los medios eléctricos de contacto para cerrar y abrir, en función del nivel del liquido a bombear, un circuito de alimentación del motor eléctrico de accionamiento de la bomba, caracterizado porque, dispuestos dentro de un espacio (4; 104) asociado a la bomba, comprende un flotador superior (13; 113) apto para cooperar con tales medios eléctricos de contacto (7, 8), un flotador inferior (12; 112) y unos medios de detención (14; 114) aptos para cooperar con el flotador inferior (12; 112) con el fin de impedir que el flotador superior (13; 113) se libere de su ajuste con tales medios eléctricos (7; 8) hasta que el empuje hidrostático ejercido por el liquido sobre el flotador inferior (12; 112) deje de ser suficiente para mantener tal ajuste.
