Working principle

The magnet, integrated in the float, switches one or more reed contacts without touching.
Vertical shape:
The float moves with the liquid level along the stem up and down and switches one or more reed contacts located inside the stem.
Horizontal shape:
At the so-called folding float switch the magnet is integrated in the hinged part and the reed switch in the fixed part. By turning the float switch, the switching function can easily be reversed (NC or NO).
