Abstract
Abstract A contact has a leg portion at one end and a resilient contact element at the other end. The resilient contact element is provided with a mother contact nose, on which an external terminal of an electronic part is to be placed, formed on its free end. A child contact nose is loosely engaged with an outer surface of the mother contact nose so that the child contact nose can be idly moved, and the child contact nose has a contacting surface larger than that of the mother contact nose.
