KARI Float Switch
– compact and reliable
The KARI Float Switch is a control device for charging and discharging pumps
and motor and magnetic valves. It is also an alarm device that alerts the
user at specified surface levels. Thanks to its large float casing (Ø
1
70 mm),
the KARI Float Switch has a buoyancy that guarantees smooth, trouble-
free operation under all conditions. SGS FIMKO Oy (the Finnish Electrical
Inspectorate) has performed testing in accordance with the Low Voltage
Directive (LVD) and approved the KARI Float Switch for use in non-flammable
liquids at 250 volts.
