ABSTRACT:
In a camera having a folding electronic flash unit, an improved dual actuator system for sequentially closing a flash charge switch to charge the flash unit's storage capacitor and operating a slider member that closes an internal switch to initiate an automatic cycle of camera operation. A charge switch actuator and slider actuator are mounted in telescoping relation for sequential operation with provisions made for optional independent operation of the slider actuator to bypass charging and operation of the flash unit. When the flash unit is folded, a detent thereon latches the charge switch actuator to inhibit inadvertent operation.
