Abstract
A member (13) with a shorting contact (14) thereon is disposed in a receptacle housing (11). The shorting contact (14) is in mating electrical contact with an interface (15). When a header (12) is inserted into the receptacle housing (11), an inclined portion (29) of a beam (28) formed on the header (12) deflects the shorting contact (14) and opens the electrical circuit between the shorting contact (14) and the interface (15). Male pin contacts (25) in the header (12) electrically engage female contacts (21) within the receptacle housing (11) before the shorting circuit is broken. When the header (12) is removed from the receptacle housing (11) the shorting circuit is closed before electrical contact is opened between the male pin contacts (25) and the female contacts (21). In this manner, spurious signals are prevented. Extension means (32) extending from the sides of the beam (28) are disposed between the shorting contacts ( 14) and the interfaces (15) assuring the opening of the shorting circuit when the header (12) is inserted in the receptacle housing (11).
