摘要：
A pressure indicator of an underwater camera housing has an indicator support surrounding an opening. An elastomer facing is united with the indicator support. The facing has a free region overlaying the opening. The free region has an inner surface and an outer surface. The free region is deflectable by a relative pressure differential between the inner and outer surfaces. Excessive inward excursion of the free region can be prevented by a backup.
