Lightbulb Light switch wiring help.

Hi everyone,

So I'm replacing a light switch. The switch currently has one black wire attached to the upper terminal screw. It is backstabbed by two black wires and one red wire. From what I can tell the two black wires originate from the same place and the red wire originates from someplace else (I wish I had x-ray vision!). The switch that I purchased only has two locations for wires to be backstabbed. I'm guessing I need a different type of switch that matches this configuration. The reason I'm writing is because I would like to understand what is going on. Also from what I can tell this switch doesn't affect the two closest plugs. Any help would be greatly appreciated! Thanks!

The backstabs are effectively being used as a splice instead of a more reliable pigtail method.
