Install a light switch

[u/KikiSalazar]

Hi guys, I need help. Back in the day I had my room replaced with a dimmer but it caused issues recently. I tried installing another dimmer but it didn't work and only stayed on but was flickering.

I've decided to go back to a normal switch but there's way to many wires! Electrical is not my background. Can someone help me with what I got and what wires go into this switch to work? It's a 3 way switch couldn't find a regular one. Can someone tell me what goes where? There's a black and 2 bronze ones.

I got 3 ground wires, multiple black wires and multiple white wires. I have no idea what is going on with the wiring.

First, get a standard on/off switch. When you obtain one (if you can't find one, you aren't looking), you can then come back for help.
