ABSTRACT:
An electronic flash unit attachable to the top of a camera shutter housing is provided with a switch control apparatus which connects with the flash unit and is positioned on the camera so as to be readily reachable by the photographer's camera-operating hand when it is in a normal position to operate the shutter and flash switch of the camera. Engagement of the switch control apparatus by the photographer's hand effects the closing of a charging switch to apply power to the flash unit and release of the switch control apparatus automatically effects the opening of the charging switch. The shutter and flash switch can be operated by the so-positioned hand as soon as the flash unit is charged.
