Battery Switche : What is it?

Battery Switches

Battery switches control the power supply from boat batteries to the engine. They allow users to switch between two batteries, or to simply switch off one battery to preserve power. They are commonly used for boats and watercraft, but they are sometimes used in cars and aircraft as well.

Choosing Battery Switches (Buying tips)

Mounting: Choose a battery switch that you can mount onto the surface or rear panel. Make sure it mounts firmly, does not slip, and can be easily removed for cleaning and maintenance.

Fuel safety:
If your boat is gasoline-powered, make sure the battery switch is safe to use with it. Check the safety indications on the package or ask your dealer for a gasoline-safe model.
