ABSTRACT:
A water-resistant housing that contains a camera has a seesaw portion which, when manually depressed at a region opposite a shutter release button of the camera, is pivoted towards the camera to depress the button and simultaneously at a region remote from the button is pivoted away from the camera. As a result, when the housing with the camera is placed under water, the water pressure balances the two regions instead of depressing the region opposite the button to possibly depress the button.
