4.2.3 Main switches

The different electronic circuits of the boat are controlled by the main switches.

The main switches allow the batteries to be disconnected from all devices that consume electricity. When the main switches are in the On position, the current is conducted to the distribution board and from there to different parts of the boat.

When the remote switches are active, the text “On” is visible and a led above the text is illuminated.

Devices that constantly need current are active regardless of the position of the remote switches.

The design drawing of the boat’s electrical system is presented in Appendix II. The location of the main switches is presented in the section Electrical system.

Power supply to the engines and devices is enabled by pulling the Start or Service switch to the lower position and pressing the On button. There is a remote switch for each engine and one switch for the service batteries. The optional bow thruster or windlass has a separate remote switch. 

The manually operated main switches are located under the aft deck, behind hatches. These switches are only for emergency use. In normal situations, use the switches in the steering console.

Current is fed to the engine by sliding the Start switch to the On position. The current feed to other equipment is achieved by sliding the Service switch to the On position, and feed to the bow thruster and windlasses is achieved by sliding the Aux switch to the On position.
