Float switches consist of a small float suspended inside your waste tank. As the water level rises or falls, the float moves accordingly. When the water reaches a specific height, the switch activates, controlling the APO pump to turn on or off. In high-waste cutoff applications, it can shut down the machine to prevent wastewater from entering the blower. Compatible with Prochem, Hydramaster, and Sapphire Truckmounts. OEM part numbers include SS-69-000S, 100719,157-091 & 29-009.
