Using this Blue Sea battery switch is easy. First, make sure to choose the right mounting option - you can mount it on the surface, rear, or front panel according to your needs. Connect the battery cables, making sure they are the right size (up to 4/0 AWG) and quantity (two cables). Tighten the terminal studs to the recommended torque of 220 in-lb (24.86 Nm). When using, you can easily tell the knob position by feel thanks to the tactile indicator. For safety, remember this switch is ignition protected, but it's still important to follow proper installation procedures, especially if you're using it on a gasoline-powered boat. As for maintenance, since it's waterproof (rated IP66), it can withstand powerful water jets. However, it's a good idea to check the terminal studs periodically to make sure they haven't loosened over time. Keep the switch clean and dry for optimal performance.
