![b-p-marine-1500x1500](https://www.rhsboating.com.au/images/com_hikashop/upload/b-p-marine-1500x1500.jpg) Description: Take a considered approach to your boat's battery controls with B-P Marine switches, isolators and relays from RHS Boating & Marine. The range includes battery isolation and selection options, compact switches, panel-mount assemblies and a voltage sensitive relay for compatible electrical installations. The right choice depends on more than the size of the switch. Compare the system voltage, continuous current rating, starting load, terminal arrangement and mounting dimensions with your installation. Battery selectors and simple on/off isolators perform different functions, so check the operating positions carefully. Each product listing provides the details needed to compare suitable options for a replacement or planned electrical upgrade.
