"It looks like you have power coming in and then going out to another outletor switch and power going thru this switch to a light."

"changing the box"
Yes
Replacing the above switch in a mobile home. Was not expecting to see 3 wire sets like this. My grandfather was looking at it saying he's never seen these before. Wondering if it was a different type of switch. We are replacing all of the outlets and switches in the house. So simple...
