  • Electrical contact unit
    Patent number: 4954092
    Abstract: An electrical contact unit electrically connects a first main member, e.g., a camera housing, with a second main member, e.g., a camera lens, which is mountable on the first main member. The first main member is provided with a contact cradle, which has first electrical contacts, e.g. pins, and a rolling or sliding member. The contact cradle is rotatably mounted on a cradle axle. The second main member is provided with second electrical contacts and a receiving recess. When the second main member is in a first mounting position, it presses against the rolling or sliding member so that the contact cradle assumes a retracted position, in which none of the first electrical contacts are in contact with the second main member.
