Title: Snap-acting float assembly with hysteresis

Abstract: A float assembly for use in actuating a switch based on the level of a fluid includes a pivot member having a pivot axis and a switching surface. First and second floats are coupled to the pivot member so that at a first fluid level the first and second floats lie on different sides of a vertical line extending through the pivot axis and the switching surface causes the switch to assume a first switching state. At a second fluid level, the first and second floats lie on the same side of the vertical line extending through the pivot axis and the switching surface causes the switch to assume a second switching state.
