Nothing\u2019s more frustrating than flicking a light switch and having the light not turn on. If you\u2019ve ruled out a burnt-out bulb, the switch itself may be faulty.\u00a0<\/p>\n
Replacing a single-pole light switch is a straightforward DIY project that takes only a few tools and a little know-how. If you have enough experience with electrical work, you may be able to do the job in just 10 to 15 minutes. However, there are still a number of safety precautions you still need to follow. <\/p>\n
If you\u2019re uncomfortable working with electricity, contact a licensed electrician to do the job.<\/p>\n
Switches work by controlling the flow of electrical current in the hot wire. Power comes in through the wire attached to the bottom of the switch, then goes out to a light or device through the wire attached to the top.<\/p>\n
Hot wires in a home are usually color-coded black or red, with neutral ones white and ground ones either bare or green. However, the switch\u2019s hot wire may also be white under certain conditions. If that\u2019s the case, it should be wrapped with black electrical tape to show that it functions as a hot wire.<\/p>\n
When you flip the switch, power flows through the switch and hot wire to the light fixture. The neutral wire returns the electricity to the panel, and the ground wire provides a safe path for excess electrical current. Always be sure to connect the ground wire properly for safety.<\/p>\n
