The Opto Switch 2 provides a way to extend the capabilities of the Delay Timer 2s or Multi-Trigger 3 to control additional cameras or flash units. The Opto Switch 2 is a significant upgrade of the earlier Camera Opto-Switch. Not only does the Opto Switch 2 eliminate all mechanical switches, but it also has the ability to control two cameras or flash units and can be chained with additional Opto Switch 2 units in order to trigger even more devices. The Opto Switch 2 doesn't have an internal power source but is instead powered by a pulse output from a Delay Timer 2s or Multi-Trigger 3. The Opto Switch 2 can also be used with legacy triggers that have pulse outputs.
Opto Switch 2
The Opto Switch 2 kit includes all the parts for the control box as well as a cable and adapter to connect to either a Delay Timer 2s or Multi-Trigger 3. Assembly is required. Experience in wiring, soldering, and troubleshooting electrical circuits is assumed. See the links to the right for more information.
The shutter cable for your camera is purchased separately. See the options below.
We provide shutter cables for most camera makes/models for use with our triggers. When you order a shutter cable, we include a 6-ft extension cable as well as an adapter to convert the cable for use with the 3.5mm stereo jack on our triggers.
Select your camera make/model below and note the corresponding ID. If you don't find your model listed, compare the socket on your camera to the photos below.
