Ball stud strategy for hand-replaceable components requiring electric power

An attachment assembly comprising:

• an electrified component having a grommet and a component electric circuit including an electrified element and an electric contact in said grommet;
• a power-supplying substrate having a substrate electric circuit;
• a conductive ball stud including a conductive anchor for attachment to said substrate circuit;
• and
• a circuit-breaking assembly associated with said stud selected from the group consisting of a photoelectric switch and an axially movable conductive tip incorporated in said stud.

A method for removable attachment of an electrified component having an electrified element to a power-supplying substrate, the method comprising:

• forming an electrified component having a grommet and a component electric circuit including an electrified element and an electric contact in said grommet;
• forming a conductive ball stud including a conductive anchor for attachment to the power-supplying substrate;
• forming a circuit-breaking assembly associated with said stud selected from the group consisting of a photoelectric switch and an axially movable conductive tip incorporated in said ball stud;
• attaching said electrified component to said power-supplying substrate by moving said grommet of said electrified component into position over said conductive ball stud and pushing said electrified component onto said conductive ball stud so that said electric contact in said grommet and said conductive ball stud make contact, thereby closing the circuit between said power-supplying substrate and said electrified element;
• and
• removing said electrified component from said power-supplying substrate by lifting said grommet off of said conductive ball stud, thereby breaking the circuit between said power-supplying substrate and said electrified element.
