Wiring a bilge pump with a float switch

This video will show you the proper way to wire a bilge pump connected to a float switch that will also operate by pushing a manual button. This will also allow the bilge pump to activate when the batteries are off.

Thanks I'm doing this today and you explained it well .I'm also wiring in a quick disconnect for the bilge motor and have the old one (still good) ready to go with the same connection for a back up.

Thank you so much. i was pondering how to do it and you solved my questions.

You could have used just one fuse had you routed the wires differently. Its easier to connect/disconnect wires together if you terminate them at a junction rather than in the middle of a wire as you have diagramed it. You have also not addressed the battery switch that is on most boats. Your automatic float switch should always be connected to unswitched power so it will operate no matter how your battery switch is set.

Very helpful. Thanks!

[@klaudiomarku6619]

won't you burn out the fuse if the float turns on the pump if you also manually turn it on at the same time?

Why not put in a unit with an internal float switch?

[@lgonzalez8635]

Is it necessary to have a toggle switch?

[@robertsonfamilyadventures7082]

Yes, you always want the ability to manually start it.

If your batteries are on will your float switch still operate manually

[@strikegoldshave]

Meaning will the float switch come on automatically when water sets it off
