摘要:<p>The threaded lampholder accepts a screw lamp bore with insulator containing main and side contacts. The side contacts are made of a highly conducting contact strip (7) on a spring supporting metal of metal alloy strip (10). Its springiness is fully retained even at high temperatures. The two strips (7, 10) rest on each other over the whole length of the springy part of the side contact. The main contact may be similarly designed. The end of the supporting strip rests on a surface of the central insulator.</p>
