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. When the second main member is in a second mounting position, the rolling or sliding member is located in the receiving recess so that the contact cradle assume a contact position, in which each of the first electrical contacts is in contact with a corresponding one of the second electrical contacts. The second main member moves from the first mounting position to the second mounting position and vice versa by the main members being rotated relative to one another.
