JOHNSON PUMP ULTIMA SWITCH Electronic Float Switch

JOHNSON's UltimaSwitch electronic float switch features micro-electrical detector cells that detect disruptions caused by water and other fluids. The cells are completely corrosion resistant and are not affected by oil or other foreign debris. The switch activates the pump when the water level reaches 50 mm or more and switches it off again when the water level drops below 20 mm. An eight second delay prevents false starts.
The UltimaSwitch switch is a highly reliable, contactless switch with no mechanical parts or toxic mercury that touch the water level and automatically controls a 12 or 24 V DC bilge pump.
