THREE-WAY SWITCH, HOUSE ELECTRICAL HARDWAREDescription: This looks like a single-pole switch except that there are two brass screws and one copper screw, and perhaps a green grounding screw. Buying information: It is used to control a light from two different locations. For example, one three-way switch could be installed at the top of the stairs to a basement, and another at the door downstairs that leads outside. You could turn on the light as you enter the basement and turn it off as you leave. In addition, you can have one switch at one end of a long hall, one at the other; one switch at one entrance to a kitchen and one at the other. |
