using OR operator in javascript switch statement

I'm doing a switch statement in javascript:

switch($tp_type){

    case 'ITP':
    $('#indv_tp_id').val(data);
    break;

     case 'CRP'||'COO'||'FOU':
    $('#jurd_tp_id').val(data);
    break;

}

But I think it doesn't work if I use OR operator. How do I properly do this in javascript? If I choose ITP,I get ITP. But if I choose either COO, FOU OR CRP I always get the first one which is CRP. Please help, thanks!
