ABSTRACT:
The shutter of a photographic camera is released in response to deformation of a diaphragm which thereby closes a microswitch to energize an electromagnet which effects release of the shutter. Alternatively, deformation of the diaphragm brings about pivotal movement of a lever which releases the shutter. The diaphragm can act directly against a movable contact of the microswitch or against one arm of the lever, or it transmits motion by way of a metallic platelike back support which protects it against excessive deformation.
