Patent ID: 7385645

Claim:
A push-button actuator for incorporation into an underwater case for photographic and/or electronic equipment comprising: a) a magnet within the air-space of the case and movably supported in a location and orientation near or in contact with or attached to a push-button on the photographic and/or electronic equipment such that motion in the direction of the magnet's North-South axis can actuate said push-button; b) a magnet external to the air-space of the case, movably supported in such a way that it may be deflected relative to the magnet within the case such that magnetic repulsive forces deflect the magnet within the case; c) a nonmagnetic waterproof separation between the magnet within the air-space of the case and the magnet external to the airspace of the case such that the waterproof nature of the case is maintained while repulsion between the magnets is allowed.
