To understand how the switch works, we can view one side of it as an example. If you remove the steering wheel (and usually the horn assembly), you can see the turn signal switches. They are usually on a plastic base plate, driven by a plastic cam, and set off by two spring steel contacts that shift contact points when the base plate is activated with the turn signal arm. | To understand how the switch works, we can view one side of it as an example.

The exact same wiring is true for the right side, with one exception: the brake lamp power is picked up from the left contact (daisy chained). | The exact same wiring is true for the right side, with one exception: the brake lamp power is picked up from the left contact (daisy chained). | ||
