Simple Jquery function syntax

Question

I want to make simple Jquery function like this:

function switchButton($param) {
 $param.on('change', function() {
  var result = $($param +'.switch-field input[name=switch]:checked').val();
  alert(result);
});
}

Execute like this:

switchButton(('.switch-field input'));

Please help to format this function correctly. Thank you.
