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.

Abstract: An electrical contact unit is provided for a first main member, which has a mainly planar first mounting surface, and for a second main member, which has a mainly planar second mounting surface and is mountable on the first main member. The first mounting surface and the second mounting surface lie against each other when the second main member is mounted on the first main member. The first main member comprises a male contact member, which has an outer surface and carries electrically conductive male contacts, and a maneuvering pin, which extends out from the outer surface. By means of guide elements, the male contact member is mounted in the first main member for motion generally perpendicular to the first mounting surface between an outer position and an inner position.

Abstract: A fishing reel of the type having a line spool which during casting is non-rotating and from which the fishing line is unwound in a substantially axial direction, a bail support member rotatable by means of a hand crank, a bail means pivotally mounted on the support member to be rotated therewith, the bail means being movable against spring action from an active position for winding up the line on the line spool to an inactive position in relation to the line for permitting undisturbed unwinding of the line during casting, a releasable latching mechanism for automatically and releasably locking the bail means in its inactive position and for automatically and releasably locking said rotatable bail support member to prevent pivoting of the bail and unintentional rotation of the rotatable member, respectively, during casting.
