Understanding the Basic Light Switch for Home Electrical Wiring
The wiring diagram shows a common electric switch also known as a light switch, wall switch, toggle switch, single pole switch or 1-pole switch.
Unless the instructions state otherwise, It does not matter which screw terminal the wires get attached to because this is just a single pole switch which means that there is one line of power that flows through the switch and it does not matter which way the electricity travels through the switch.
With this type of switch the electricity comes in through one connection and flows out through the other.
If you wanted to be logically correct you could wire the switch so the power comes in the bottom and out the top as the direction of travel of the position of the switch.
Some electrical devices are wired so the power enters the top and travels downward and leaves the controlling device through the bottom connections, however it really does not matter to the electrical wiring of this type of switch as long as the electricity is getting to the light fixture or the electrical device you are controlling.
