ABSTRACT:
An underwater camera or instrument having a depressible shutter release button or similar actuator is housed within a flexible plastic waterproof housing. A toggle lever is mounted on the camera with one end overlying the button. Surrounding the lever is a frame member that extends upwardly to separate the housing from the lever so as to prevent water pressure acting on the housing from applying a force on the button.
