I'm replacing the switch for my garbage disposal. It has a red wire on the left and a black wire on the right. I'm replacing it with a switch interrupter that has both screws on one side and a ground on the other. Which wire goes on the top screw and what do I do about a ground?

Thanks!

Connect the 2 screws to either terminal, it dosen't matter if the screws are top and bottom or right and left, connect ground to ground on switch(It is the body of the switch).
