Why does my light switch only have two wires?
1 Answer. Yes, this is normal. There are two ways to wire a two-way switch with 2-core cable like you have: one where the switch is between the supply and the light fixture(s).
Where does black wire go light switch?
The black (hot) wire goes to the brass screw or into the hole in the back of the device on the same side as the brass screw. This wire is sometimes red. The green or bare copper (ground) wire, if the device has one, attaches to the green screw terminal on the switch or to the electrical box.
