  • Patent number: 4655516
    Abstract: An electrical connector in the form of a chip carrier connector comprises a dielectric frame having electrical terminal posts secured therein, top sections of the terminal posts extending above a top surface of the frame and bottom sections of the terminal posts extending outwardly from a bottom surface of the frame for insertion into respective holes in a printed circuit board, a film of dielectric material initially disposed adjacent the bottom surface of the frame and having the bottom sections of the terminal posts extending therethrough. The dielectric film is movable along the bottom sections to a position adjacent the ends of the bottom sections thereby aligning the ends of the bottom sections with the respective holes in the printed circuit board so that the bottom sections can be inserted into the respective holes.

  • Patent number: 4599497
    Abstract: An electrical switch comprises a dielectric housing along one side of which movable electrical contact members are disposed. A stationary electrical contact is disposed along the other side of the dielectric housing. Each of the movable contact members has a curved contact section, one end of the contact section being secured in the dielectric housing as a terminal section while the free end of the contact section is disposed within a recess of an actuating member pivotally mounted on the housing with actuating sections of the actuating members being operable from one surface of the housing to one position thereby moving the curved contact sections in electrical engagement with the stationary contact and to another position thereby moving the curved contact sections free of the stationary contact, the spring forces of the curved contact sections maintaining the actuating members and the contact sections in the one or the other position.
