Abstract
Abstract A REED SWITCH, RESPONSIVE TO AN ELECTROMAGNETIC FIELD, IS ATTACHED TO A CONDUCTOR AND IS CLOSED WHEN THE ELECTRIC CURRENT THROUGH THE CONDUCTOR REACHES A PREDETERMINED VALUE. SINCE THE CURRENT THROUGH A BUS BAR (CONDUCTOR) THAT SUPPLIES ENERGY TO AN ELECTROPLATING BATH VARIES AS THE TOTAL SURFACE AREA OF THE PARTS BEING PLATED VARIES, CLOSURE OF THE REED SWITCH IS INDICATIVE OF THE FACT THAT A PART OR GIVEN NUMBER OF PARTS HAS PASSED THROUGH THE PLATING BATH.
