Latching magnetic float switch

Abstract

A latching magnetic float switch with a single fastener mounting clamp and pivoting toggle bar magnet interrupting an electrical circuit to stop fluid production once actuated by an initially offset float magnet first rotating a small distance in response to liquid accumulation in the collection pan upon which the switch is mounted, the float magnet then achieving a strong snap-locked latching magnetic engagement with the toggle bar magnet solely through building magnetic attraction between them, engagement continuing until the float magnet is manually reset into its original offset positioning. The 2-part clamp with a rotating curved/bowed clamp arm can mount the switch securely to both metal and plastic liquid collection pans with differing draft angles, and also provides a clamp base configured for elevation adjustment of the float housing relative to pans having different wall height dimensions and fluid production shut off when detected fluid depth is less than 0.5 inches.
