ABSTRACT:
A quick assembly shield for electrically insulating the front surface of an electrical control device includes a flexible generally rectangular body having a top retainer including a step for engaging the lip of a lug on the top surface of the control device. A pair of laterally interfering surfaces are provided for longitudinally aligning the shield with respect to the underlining control device. A spaced pair of inwardly facing catches engage in snap fashion a laterally spaced pair of lugs on the lower surface of the control device. The shield can be quickly and positively engaged with the underlying control device yet still provide access to permit variance in temperature or other control functions as required.
