Abstract
An underwater housing for photographic cameras, comprising a camera housing portion, a closure portion detachably connected with the camera housing portion, actuation elements for operating the camera penetrating through the wall of the camera housing portion. One of the actuation elements comprises a pusher arrangement for releasing the camera shutter which incorporates a pressure pin and a seal formed of elastomeric material inserted into an opening in the wall of the camera housing portion. The seal is provided with a head, a ring flange and a plug elastically expansible in lengthwise direction. The plug and the ring flange extend so as to protrude concentrically with respect to one another from the underside of the head. A peripheral groove is formed at the outer surface of the ring flange into which protrudes the wall portion of the camera housing portion surrounding the opening. A blindhole bore extends from the upper side of the head into the plug, and in the blindhole bore there is held the pressure pin.
