Electrical Wall Switches
There are many different types of
light switches in your home that can go to controlling your light
fixtures or electrical outlets. There are single pole switches that can
control things from a single location, three-way switches that control
lighting our outlets from two locations (that are popular in larger
homes or with more complicated room situations), and even four way
switches that may be used to control switches from three or more
locations in the home.
