If you want to check which button has been clicked and you are going to have multiple buttons, you can use $(this) inside the .click(), it will reference THE object which was clicked. So change the switch to:
switch($(this).attr('id')) {
The full lot:
$('#buttons button').click(function(){
switch( $(this).attr('id') ){
case "mail":
alert(1);
break;
}
});
See a working demo here
change
$('buttons').id
to:
$('buttons').get(0).id
