ABSTRACT OF THE DISCLOSURE An electronic flash unit attachable to the top of a camera shutter housing is provided with switch control apparatus which may be selectively extended into position so as to be engaged by the photographer when holding the camera in its normally expected manner. Engagement of the switch control apparatus by the photographer causes it to effect the closing of an ON-OFF switch thereby applying power to the flash unit whereas subsequent disengagement of the switch control apparatus causes it to automatically effect the opening of the ON-OFF switch.
