Switch Statement Question

I need to write the switch statement below in a way where I can have each case with multiple values, and avoid using "break;" to allow the evaluation of the rest of cases. the code below should jump into the first 2 cases but not the last one, but it is not doing that. Is there a way for me to get around this.

function test(){
var Temp = 'cs1'

switch(Temp){
case 'cs1' , 'cs2':
alert(Ƈ');

case 'cs1':
alert(ƈ');

case 'cs2':
alert(Ɖ');
}
}
