Switch causes Unreachable code

[osimicek]

When I write this code:

var trySwitch = function(num) {
    switch (num) {
        case 1:
            console.log("OK", 1);
            break;
        case 2:
            console.log("OK", 2);
            break;
        case 3:
            console.log("OK", 3);
            break;
        case 4:
            console.log("OK", 4);
            break;
    }
};

on the lines 6,9,12 tslint shows error:
"Unreachable code"
This is caused by break statements.

I found this error only in tslint@0.2.4
