The original set up was voltage came into the switch and when the pedal was pressed it went out to the stop lights. With the signal switch, IF you are using the brake lights as signal light too, then the power gets sent through the signal switch so it can dictate what light blinks and what shines as a stop light. If you are using separate lights for the signals then you can skip the brake switch.
