Breaking out of a switch from in an if

I have this code snippet:

switch (userInput){
        case "a":
        case "A":
        case "ARC Gun":
        case "arc gun":
            var conf = confirm("Are you sure?\n Wieght: 3\nMax Ammo: 5 clips");
            if (conf){
                alert("The ARC Gun it is!");
                wieght += 3;
                break;
            }else if (!conf){

            }
    }

Will the break statement break me out of the switch block? Or out of the if, or nothing?
