We have a new float switch in the bilge that pumps out when activated
at a certain level.

There is also a switch on the panel.

Previously, the switch on the panel supplied power to the bilge pump
switch, so that if the panel switch was off the pump would not run, no
matter what level the float switch. ie. they were in series.

I think the common practice is to use a three-position panel switch -
On/Off/Auto. This allows you full control of the pump - you can force
the pump on, regardless of water levels, prevent it from operating at
all, or allow the bilge switch to control it. Obviously, the switch
would normally be left in the "Auto" position, giving the bilge switch
control.
