Pull a 12-gauge cable from the power source, making sure that the power is off and the cable is dead. Feed it through the back of one of the switch boxes and strip the wires. Run a second 12-gauge cable from the first switch to the second one and strip the wires on both ends.

Can I use Relay for switching?

Relays are generally used to switch smaller currents in a control circuit and do not usually control power consuming devices except for small motors and Solenoids that draw low amps.

How do I get power to another switch?

If you need to provide power to an outlet or another switch, you can tap into either the live wire from the panel on the existing wall switch, or the switched wire, should you desire that the new element be controlled by the switch.

You can pull power from a switch box—sometimes Switch boxes can sometimes be used as a power source for a new outlet, but only if the box is large enough and has neutral and ground wires running through it.

How can I switch between two power sources?

Portable equipment that can operate from a battery pack or an external power source (such as a wall-adapter or external supply) needs to be able to smoothly switch between the two power sources. This application note describes a circuit ( Figure 1) that switches power sources with good efficiency and without switching noise.
