ABSTRACT:
An electrical contact assembly of the present invention includes a body having a housing and a cover defining a space. A pair of spaced terminals are received in the space. One of the terminals has a contact formed at a free end thereof. The other contact has a spring arm secured to its free end. A contact is mounted on the spring arm in a position in which it can be moved into contact with the first contact. An extension is provided on the spring arm and a stop is provided in the body. When contact operation causes or attempts to cause tack welding of the two contacts, the stop extension operation maintains a spring force on the spring arm sufficiently strong to break the tack weld so that the contacts can be opened.
