THE WIER CAN BE SUPPLIED IN A PREDETERMINED LENGTH AND THEN FORMED INTO A U-SHAPE BY MEANS OF PLIERS, WITH THE LEG PORTIONS OF THE U-SHAPED WIRE THEN ENGAGED BY THE FRICTION GRIPS. THE SWITCH IS CLOSED AND THE WIRE HEATED WITH THE WEB PORTION BETWEEN THE LEGS PRESSED INTO THE FRAME ACROSS THE BREAK.
