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.

Famous quotes containing the words lighting, pole, circuit and/or switches:
“There is no more miserable human being than one in whom nothing is habitual but indecision, and for whom the lighting of every cigar, the drinking of every cup, the time of rising and going to bed every day, and the beginning of every bit of work, are subjects of express volitional deliberation.”
—William James (1842–1910)
“The discovery of the North Pole is one of those realities which could not be avoided. It is the wages which human perseverance pays itself when it thinks that something is taking too long. The world needed a discoverer of the North Pole, and in all areas of social activity, merit was less important here than opportunity.”
—Karl Kraus (1874–1936)
“We are all hostages, and we are all terrorists. This circuit has replaced that other one of masters and slaves, the dominating and the dominated, the exploiters and the exploited.... It is worse than the one it replaces, but at least it liberates us from liberal nostalgia and the ruses of history.”
—Jean Baudrillard (b. 1929)
“I find television very educational. Every time someone switches it on I go into another room and read a good book.”
—Groucho Marx (1895–1977)
