A 3-position boat switch has three distinct positions: on, off, and on. This allows you to control the power to two devices separately. When the switch is in the centre position, both devices are off. If you move the switch to one side, one device turns on while the other remains off. Moving the switch to the other side turns the first device off and the second device on.

What You'll Learn
Wiring a 3-position switch
A 3-position boat switch has three distinct positions: on, off, and on. This allows you to easily select the desired setting for your electrical systems. To wire a 3-position switch, you need to understand how the pins are connected to each other in each position.
In the up position, pins 5 and 6, and 2 and 3 are connected. In the down position, pins 2 and 5 are fed, and the light comes on. If you also want the pump to come on in the down position, you need to jump the pins so that they are both fed.
If you want to control two separate devices with the switch, you can put one device on pin 1 and the other on pin 4. In this setup, when the switch is in the up position, device 1 will be on and device 2 will be off. When the switch is in the down position, device 1 will be off and device 2 will be on. When the switch is in the centre position, both devices will be off.
It is important to note that circuit drawings do not always indicate the actual mechanical operation, so it is best to check with an ohmmeter before hooking up the switch to verify the connections.

Using a 3-position switch to control two devices
A 3-position boat switch has three settings: off, on, and on. This means that you can use it to control two devices independently. When the switch is in the off position, both devices are off. When it is in the first on position, device one is on and device two is off. When it is in the second on position, device one is off and device two is on.
You can wire a 3-position boat switch to control two devices in a few different ways. One way is to use the switch's up and down positions to control the devices. In this setup, when the switch is in the up position, device one is on and device two is off. When the switch is in the down position, device one is off and device two is on. This can be achieved by jumping the pins so that pins 2 and 4 are the feed and pins 1 and 3 are connected to the load.
Another way to wire a 3-position boat switch is to use the centre position to control both devices. In this setup, when the switch is in the centre position, both devices are off. When the switch is in the up position, device one is on and device two is off. When the switch is in the down position, device one is off and device two is on. This can be achieved by jumping pins 2 and 5 so that they are both fed and then backfeeding the second feed pin with the current from the other device.
It is important to note that the circuit drawings do not always indicate the actual mechanical operation of the switch. It is best to check with an ohmmeter before hooking up the switch to verify its functionality.

The 'up' and 'down' positions of a 3-position switch
A 3-position boat switch has three distinct positions: on, off, and on. When the switch is in the up position, it turns on one set of devices, and when it is in the down position, it turns on a different set of devices. When the switch is in the centre position, all devices are off.
For example, if you have two devices connected to the switch, when the switch is in the up position, device 1 turns on, and device 2 stays off. When you move the switch to the down position, device 1 turns off, and device 2 turns on.
The specific functionality of a 3-position boat switch can vary depending on the wiring and the devices connected to it. In some cases, the switch may control lighting or other electrical systems on the boat.

Using a 3-position switch with a different feed for each device
A 3-position boat switch has three distinct positions: on, off, and on. This allows you to control two devices separately. When the switch is in the centre position, both devices are off. If the switch is moved to the first 'on' position, device one will turn on, while device two remains off. When the switch is moved to the second 'on' position, device one turns off, and device two turns on.
You can wire a 3-position switch to use a different feed for each device. For example, pins 1 and 4 can be used when the switch is in the up position, and pins 3 and 6 can be used when the switch is in the down position. This allows you to control which device is active, depending on the position of the switch.
The functionality of the switch can be tested by jumping the pins so that they are both fed. This will cause the light to come on when the switch is in the down position, and the light and pump to come on when the switch is in the up position. However, this method may cause both LEDs on the switch to light up, which can be avoided by backfeeding the second feed pin with the current from the other device.

The on and off settings of a 3-position switch
A 3-position boat switch has three settings: off, on, and on. When the switch is in the off position, all devices connected to it are turned off. When the switch is in the first on position, device 1 is turned on, while device 2 remains off. When the switch is in the second on position, device 1 is turned off, and device 2 is turned on.
The functionality of a 3-position boat switch can be customised to suit specific needs. For example, it is possible to wire the switch so that both devices are on when the switch is in the first on position and only device 2 is on when the switch is in the second on position.
The Blue Sea Systems Contura 3-position boat switch is a popular option for boaters and fishermen. This switch has an off position and two separate on positions. When the switch is in the first on position, device 1 is turned on, and device 2 remains off. When the switch is in the second on position, device 1 is turned off, and device 2 is turned on.
The Fairbank method of wiring a 3-position boat switch involves jumping pins 2 and 4 and putting load A on either pin 1 or 3. Load B goes to pin 4, and pin 6 is left empty. With this setup, pins 1 and 4 work when the switch is in the up position, and pins 3 and 6 work together when the switch is in the down position. When the switch is in the centre position, everything is off.

Frequently asked questions
The three positions are: on, off, and on.
When the switch is in the first position, device 1 is on and device 2 is off. When the switch is in the second position, device 1 is off and device 2 is on. When the switch is in the third position, both devices are off.
There are a few different ways to wire a 3-position boat switch, depending on the specific switch and application. One method is to jump the pins 2 and 5 so they are both fed, which will turn on the light in the down position and the light and pump in the up position. Another method is to backfeed the second feed pin with the current from the other device being on, which will turn on the light in the down position and both devices in the up position.
