The power runs from the headlight switch to the high low switch, then to the headlamps. If the high low switch on the floor is only making contact on the high side, then the low beams will not come on. In other words, the power from the headlight switch goes to a common on the high low switch, then the high low switch has 2 outputs, one goes to the low beam and the other to the high beams. Each time you press the floor high low switch the headlights toggle from high to low and back again.
