Abstract: A float switch used for system shut-off and/or alarm activation in response to fluid detection. A clamp connects the switch's protective housing to a fluid-collection pan wall, with the switch comprising a pivoting float assembly having a magnet originally positioned out-of-phase to an upper magnet on a toggle, a contact spring and ferrous pin also diminishing attraction of the magnets toward one another until the float assembly is sufficiently raised by accumulated fluid to force the upper magnet away from the ferrous pin and instead engage the lower magnet, the toggle promptly shifting position so that its opposite end may close a circuit that activates an alarm, remote notification, or other communication/control. The exponential increase in attractive force between the magnets as they draw near to one another results in a very rapid snap action that reduces malfunction. Manual reset of the toggle and float are required for continuing/repeat use.

Abstract: A small compact magnetic latching shut-off switch having a lightweight float, angled geometry, and quick/convenient small-stroke manual float reset. A lower float magnet and a second upper magnet affecting electrical circuit continuity have initial offset positioning that minimizes their magnetic attraction to one another. When a predetermined small amount of fluid accumulates below it, the float begins forward rotation and attraction between magnets thereafter multiplies until gravitational force on the float and forces maintaining initial raised positioning of the upper magnet are overcome, resulting in strong latched snap-lock connection between upper and lower magnets, an abrupt/reliable/strong tripped state that remains until manual float reset occurs. Transparent float housing reveals drain line clogging potential, and structural features of the float and housing enable raised tripping point adjustment, promoting switch reliability.
