ABSTRACT:
A release member and a latching member are pivotably mounted in juxtaposition to a pivotable shutter operating member. The release member and the latching member are spring biased to latch the shutter operating member to shutter non-operating position and the release member to a position where it maintains the power switch contacts open for controlling the power drive of the shutter. Limited play between the release member and the latching member permits the switch contacts to close prior to the latching member releasing the shutter operating member and the shutter operating member in turn, when moved to shutter operating position, maintains the release member in release position to maintain the power switch contacts closed.
