Replacing light switch plus adding a new one
I live in an older house. I am replacing a single pole light switch with a smart switch. The current switch has 2 black wires going into it (one into the top screw and 1 into the bottom screw). It also has 1 wire black wire going out from the bottom screw that connects to other black wires coming from the box. All of the white wires in the box are connected together. There are no ground wires. Which wire would be the load wire? Thanks.
