The externally located combined push button and rotary switch is operable to select and adjust lens control parameters by a user wearing bulky hand protection such as welding gloves or welding mittens. The selection and adjustment level of the lens control parameters can be monitored on the display during the adjustment by a user while the lens is in the lowered operational position.一種例如為焊接頭盔的自動調暗眼睛保護設置，其包括外部設置的組合的按鈕及旋轉開關，其與控制電路連接。鏡片控制設置顯示器設置在設備的內部上，並在鏡片處於較低操作位置時處於使用者的視線範圍內。佩戴龐大手部保護，例如焊接套或者焊接手套的用戶可對外部設置的結合按鈕以及旋轉開關操作來選擇並調節控制參數。用戶可在鏡片處於較低操作位置時的調節過程中在顯示器上監控控制鏡片控制參數的調節水準。
