Waterboy Tank Float Switch
The Waterboy Tank Float Switch is a simple, durable, long lasting and easy to use device for filling or
emptying your water tank or storage vessel.
The float switch is a, ball activated lever switch enclosed in a durable, water proof casing.
To install, it is simply lowered into the tank and suspended via its cable, it only needs to pivot up and
down on the weight supplied in order to function.
You may need to adjust the position up or down in the tank until the desired level is reached to have
the switch floating vertically when the tank is full.
The float switch comes with 20m of cable making it the perfect way to remote switch over a short
distance.
Selecting 2 of the 3 wires available (BLUE, BLACK, BROWN), are all that is needed for N.O. (normally
open) or N.C. (normally Closed) terminal contacts based on float up or down position (see below).
