Should I install a new junction electrical box when moving a light switch?

When you install a new light switch, you need connect wires that run from the junction electrical box to the switch. Installing a new junction box can be expensive, but it may not be necessary when installing a new light switch. Rather than having a new junction box installed, analyze the layout of the area between the junction box and the new light switch location. If you can pull the wires through from the junction box to the new light switch by drilling a small hole in the wall or ceiling, you can save yourself money and time with your installation.
