<human>:  How do I fix a broken light switch?
<bot>: To fix a broken light switch, you will need to switch off the power in the room and then carefully remove the switch from the wall. If the switch is broken, replace it with a new one that matches the size and type of the old one. Then, be sure to reattach the wires to the same terminals they were connected to before and securely tighten all screws. Finally, restore power and test the light switch to make sure it works.
