First if condition checks whether toggle is switched to desired side. Condition can be changed according to requirement. Last jquery is to make toggle button grey.

 if(!$('#togglehk').is(":checked"))
                    {
                        $('#togglehk').click();
                    }
  jQuery('#togglehk').attr("disabled", true);
  jQuery('#togglehk').prop("disabled",true);

  jQuery('#togglehk').next(".slider").css("backgroundcolor","#B3B3B3");
