FLOAT SWITCH AND PANEL CHART
The purpose of this chart is to show the required switch
quantities and the function of each switch in a typical
wastewater system. The quantities required vary de-
pending on the switch type, single-action or wide-angle.
Switch quantities also vary by panel type: simplex with
and without alarms, and duplex with alarms.
