RTM - Model LS-300 -Pump Level Switch

RTM`s Pump Switch is a non-contact level sensor that controls wastewater pumps. You simply plug your pump into the LS-300 and the sensor turns your wastewater pump on when the liquid level rises to Level 1 and off when the wastewater lowers to Level 2. The switch shown above turns the pump on with 3` of liquid and off with 1` of liquid in the tank or reservoir. It also has a built-in timer that allows your pump to stay on for an additional 10 seconds after the low level is met to completely drain the tank.
