High Quality and Reliable Float Switches

Kari Finn are a well established manufacturer of high-quality surface switches, multi-pole connectors and pump starters.

Kari float switches are cable-suspended free floating control devices. They are used to detect and control wastewater levels, liquids generated by industry, liquids with varying degree of viscosity, liquids in wells, pump systems and tanks.

A control weight fixed to the cable keeps it immersed in the liquid, causing the switch to tilt in line with fluctuations in the liquid level The revolutionary design avoids the need for several single-point float switches in one tank, preventing the risk of tangling as liquid level rise and fall.
