When the float becomes afloat by the change in the surface, the internal balance weight instantly moves to the other side, and because of the rapid change in the center of gravity, the float turns upside down, and operates the micro switch or the mercury switch in order to show the electric contact and control the level.
SQM: Activation of the switch takes place when the reed switch passes through the center of the doughnut shaped magnet.
SQH: Micro switch lever is activated by the weight of a rolling ball within a capsule inside the tilting float.
