Magnetic switch, ON/OFF, bistable
The magnetic switch is mounted outside of the float chamber opposite to the
indication rail. The switching logic can be reversed by inverting the switch
module with cable-exit upwards or by installing the switch module adjacent to
the indication rail where technically authorised (see datasheet 20010501).
The magnet inside the float activates the reed switch, when the liquid in the
float chamber reaches that level.
