This floating switch is designed for mounting from the top. This is fitted with a built-in weight for fixing the switching point at the desired height; this renders additional fastening of the switch at the height of the switching point unnecessary. This weight is dimensioned in such a way that the switch tilts around its own axis when the liquid level rises and then follows the rising liquid level. This tilting action of the float activates the switching process. This unit is not suitable for use in turbulent liquids (e.g. in stirrer tanks).
