Abstract
A button for use with an image capture device in an underwater environment that includes a movable plunger configured to cause actuation of the image capture device and upper and lower components collectively defining an internal cavity that is configured to receive the plunger. The upper and lower components are configured and connected such that actuation of the image capture device is prevented until a threshold pressure is applied to the upper component that is greater than external water pressure applied in the underwater environment. The upper component includes at least one opening that is configured to allow water to enter the internal cavity to modify an internal pressure within the internal cavity so as to reduce the threshold pressure required to actuate the image capture device in the underwater environment.
