T21 tandem models combine the functions of two separate narrow differential level controls in a single, compact, easy to install instrument. Two independent switch mechanisms are employed to provide two actuating levels at least 8" apart, such as high and low level alarm operation.

Model T21 tandem float switches are available with optional cages to help stabilize the floats under turbulent conditions.
