Device for extending short individual signal of shutter release cable of camera to multiple short signals, has output shutter release jack outputting multiple short signals so as to simultaneously activate all cameras connected in parallel

摘要

The device has a control panel (29) comprising isolated switches (34-43) connected between shutter release jacks (44-48) e.g. input and output shutter release jacks. A direct current input (32) supplies electricity to the switches. An energy source (30) provides energy to the input. The input shutter release jack transmits an individual short signal (31) to the switches and activates the signal so as to extend the signal to multiple short signals. The output shutter release jack outputs the short signal so as to simultaneously activate all cameras (49-53) connected in parallel.
