How do you properly wire a light switch in a residential electrical system?

To properly wire a light switch in a residential electrical system, you need to first turn off the power to the circuit. Then, connect the hot wire (usually black) to the brass screw terminal on the switch, and the neutral wire (usually white) to the silver screw terminal. Finally, connect the ground wire (usually green or bare copper) to the green screw terminal on the switch. Make sure all connections are secure and the switch is properly installed before turning the power back on.
