При монтаже выключателя света нужно руководствоваться главным образом удобством доступа к нему. Чаще всего он устанавливается рядом с дверной коробкой так, чтобы открытая дверь не мешала включить свет. Высота установки обычно составляет 1 – 1,5 м от пола. Однако в некоторых случаях рациональнее поднять выключатель на высоту человеческого роста. Например, когда в помещении есть предметы мебели и интерьера, которые будут загораживать выключатель при установке внизу. Не рекомендуется располагать его в зоне, подверженной попаданию воды. Поэтому обычно выключатели на ванные и туалетные комнаты выносят в прихожую.
