ABSTRACT:
In a switch device having a reed switch activated by a magnet carried by a first float, the differential between the reed switch being activated and de-activated is increased by providing a second float vertically spaced from the first float and arranged to hold the latter against switch de-activating movement when the liquid level changes and until the liquid level is such that the level of the second float changes to a predetermined level.
