PURPOSE:To obtain a multi-point controlling function which permits optional selection of single shot and continuous shots by connecting simple circuit blocks in parallel and operating the same with an operating part. CONSTITUTION:Two switch elements T1, T2 are provided in parallel with a bulb switch S3 to a control circuit. The element T1 stops winding in the stage of one shot and starts and stops a motor M by means of a trigger switch S1. When the switch S2 is closed in the stage of continuous shots, the motor M can be run continuously. The element T3 is serviceable for adjusting the intervals of continuous shots in the stage of continuous shots and the time when the element T3 conducts is created by an R.C time constant circuit. Then, the multi-point controlling function which permits optional selection of one shot and continuous shots is obtained. |
