A bilge pump is an essential tool that helps keep the boat afloat whenever it starts taking on water. It works by quickly pumping out water from inside the boat, subsequently keeping the small vessel high and dry. Nevertheless, for the pump to function effectively, it requires a float switch.
As the name implies, a float switch is a device that triggers the bilge pump on whenever there is excess water in the boat and then turns the pump off once the boat is dry. The float switch detects the level of water in the pump before automatically switching it on and off, accordingly. If the float switch is malfunctioning, your boat could sink.
So what is the best bilge pump float switch? Here is a list of 5 different float switches you could consider for your boat.
