On-Off-Combine switches, also known as On-Off-Both switches, are a type of boat battery switch that offers simplicity and passive control over the battery system. They have three positions: Off, On, and Combine. When the switch is in the Off position, it is completely disconnected from the battery, preventing any electrical current from flowing. In the On position, both circuits close at the same time but remain isolated from each other. The Combine position allows both batteries to work together, providing additional power and extending the life of the batteries.

The ON-OFF-COMBINE switch allows users to choose which battery to use and when
The ON-OFF-COMBINE switch, also known as the ON-OFF-BOTH switch, is a type of boat battery switch that offers simplicity and control over the battery system. It has three positions: OFF, ON, and COMBINE. When the switch is in the OFF position, it is completely disconnected from the battery, preventing any electrical current from flowing. In the ON position, both circuits 1 and 2 close (connect) at the same time but remain isolated from each other. This means that the two batteries act as two isolated single-pole switches in one housing.
The ON-OFF-COMBINE switch offers more control over the boat's electrical system than the ON-OFF or 1-2-BOTH switches. It allows the user to choose which battery to use and when, providing increased flexibility. For example, in the COMBINE position, both batteries can work together, providing additional power and extending the life of the batteries. This is particularly useful in emergency situations, such as a dead battery or a fire, as the switch can be used to isolate one battery from the rest of the system, preventing damage or potential safety hazards.

The ON-OFF-COMBINE switch offers more control over the boat's electrical system than the ON-OFF or 1-2-BOTH switches
The ON-OFF-COMBINE switch, also known as an ON-OFF-BOTH switch, offers more control over a boat's electrical system than the ON-OFF or 1-2-BOTH switches. It has three positions: OFF, ON, and COMBINE. In the OFF position, the switch is completely disconnected from the battery, preventing any electrical current from flowing. In the ON position, both circuits 1 and circuit 2 close (connect) at the same time but remain isolated from each other. This means that the user can choose which battery to use and when, providing greater control over the electrical system. The COMBINE position allows both batteries to work together, providing additional power and extending the life of the batteries. This increased flexibility means that the ON-OFF-COMBINE switch offers more control than the ON-OFF switch, which simply completes an electrical circuit to the motor when it is on, and breaks the circuit when it is off. It also offers more control than the 1-2-BOTH switch, which allows the user to choose between one of two batteries or both batteries combined, but does not offer the same level of isolation as the ON-OFF-COMBINE switch.
