将Bootstrap开关与另一个元素对齐

Question

所以我有这些元素，如图所示...

<style> 
         .btnautodesigner {
                   margin-left: 5px;
         }

        .form-group-centered {
              width: 400px;
         margin: 0 auto;
        }

         </style>

            <div class="form-group row">
             <div class="col-xs-12">
                <div class="form-group-centered">
                    <div class="input-group pull-left" style="width: 220px;">
                    <span class="input-group-addon"> <input type="checkbox" id="allowbreak"> Break After </span>
                    <input type="text" class="form-control" id="c_count" value="20" onblur="c_count_onblur()" style="text-align: center;">
                </div>

                <button id="btnautodesigner" type="button" class="btn btn-default btn-md btnautodesigner pull-left" style="">Autodesigner</button>
                </div>
                <input type="checkbox" data-toggle="switch" id="split_state" data-handle-width="75" data-on-text="Split" data-off-text="Do Not Split">
             </div>
            </div>

我目前有以上代码。我该如何编码使其具有以下输出？

抱歉，我似乎无法弄清楚。我尝试将开关移到不同的部分，但是会产生奇怪的元素排列。谢谢。

如果全屏运行code snippet，您将看到它们以horizontally为中心

实时演示：https://jsfiddle.net/czaL5wyf/

.center-me {
  position: absolute;
  left: 50%;
  transform: translate(-50%, 0);
}
