Float Switch
Single or dual control float switches (Figure 6) can be used for the unattended operation of the submersible pump. When using the
piggy-back power configuration (plug), the pumps DO NOT require the use of a control box. In this configuration (piggy-back), the
SW-1 (single float switch) or SW-2 (dual float switch) are required. The illustration below is an example of a single float switch application.
