The “Switch Mate” single piggyback variable level float switch (VLFS) allows you to convert a 115 V nonautomatic pump into an automatic pump. Additionally, the piggyback float switch allows you to adjust the on and off point within the tank. So, it is ideal for deeper basins and pump tanks. The piggyback float switch is constructed of PVC and polypropylene. The materials of construction enable the switch to withstand the harsh wastewater environment. The standard cord length is 15′ which is more than enough for most basin or pump tank applications. It is also a normally open mechanical float, so it can be used to pump the level down in a pit or tank.
