The reverse switch: Principle and Connection

The principle of the reverse switch is to allow 2 different circuits when being in position 1 or 2.
You can then connect a motor and ensure that the polarity is changed by switching from position 1 to 2.

It's easier to understand on the following diagram:

We checked the internal connections of the terminals of the reverse switch using an ohmmeter. This showed us that:

• in position 1: terminal 2 is connected to terminal 1 and terminal 5 is connected to terminal 4
• in position 2: terminal 2 is connected to terminal 3 and terminal 5 is connected to terminal 6

We then connected the solar panel and the motor as indicated on the diagram above, reversing the polarity at motor's terminals when changing switch position.
