You know when you need a light switch replacement when the switch simply does not turn on the light anymore or the light flickers when turning it on. Light switches that builders and electricians install in homes are the most inexpensive available on the market and their service life is about three years if the switch is located on a light circuit that is frequently used such as in kitchens, bathrooms, and entryways. They cost less than a $1.00 each, whereby good quality light switches cost approximately $2.50 or more and will last for ten or more years.

There are three basic types of light switches used in homes:

1. Single pole switch which is the most common switch. It is identified by two wire terminals plus a ground wire. The toggle on a single-pole switch is clearly marked “On” and “Off”.
2. Three-way or four-way switch is not marked “On” and “Off” because it depends on the other switch (s) in the circuit as to it is “On”  or “Off” being in an up or down position. They have three wire terminals plus a ground wire. This type of switch works in tandem with another three-way or four-way switch so power can be turned on and off from two or more different locations.
3. A Dimmer switch type of switch dims or raises the lighting level.  

Remove power from the light switch by turning off the circuit breaker that feeds the switch. It may be labeled in the circuit breaker box, if not, turn the light switch on and off to ensure you have the correct circuit breaker. If the light goes out you have the correct breaker. If you are not positive check for voltage once the light switch wiring is exposed.
