Lighting and Pole Circuit Switches
Usually located close to the overhead switch will be the light switches, which normally switch on both the interior lighting and the headlights. Double ended trams also have a switch to energise only the headlights at the end of the tram facing forwards. Trams with two trolley poles, may also have a pole circuit switch which ensures that only the pole on the overhead wire carries a current. Trams with pantographs will have a console switch or button to raise or lower the pantograph.
