Battery Switches & Isolators

Battery master switches and isolators to safely disconnect your system.

A master switch lets you kill power at the battery for servicing, for long-term storage, or in an emergency. It is also the simplest way to stop parasitic drain flattening a battery while a caravan or boat sits unused.

Mount it as close to the battery as practical and size it to the full current the circuit can carry, not the average draw.
