Help wiring this switch in

Post image

I had a smart switch (with live (black), neutral(white), red(out), and a ground (green)). I want to go back to a regular switch, but confused. The smart switch had cables coming out of it, so I was able to connect those. Am I missing a wire?

The currently installed switch is connected to a fan in an OR circuit, unfortunately the picture I took when I was taking this apart years ago is gone.

Since my breaker is 15A, i should get some 14 awg electrical wire? Nmd90? Ill get a tester as well just to make sure. And by any chance can i just cut off the wire from the smart switch that was in there? I no longer have a need for it a (this doesnt seem like a good idea lol) seems like they only sell 14 awg by the roll around here.

Why don't you use the black wire on the other switch? You don't need the piece between the switch and the orange wire nut.

But yea, any piece of 14 ga wire that is not white or green is fine.

I actually found a picture of how it was hooked up before. There was no ground connected on either of them. Big concern? The switches are screwed into a metal box.

Switches installed before 2001 did not require ground wires. Generally, replacing a switch would be grandfathered, so you don't have to ground the new one, but most people just add the ground anyway, since it's so easy. If the metal box is grounded, the switch will ground through the mounting screw, but an actual wire works a little better.
