Wiring
As this is an electrical switch and not pneumatic, I scanned many a pic to see what the cable looked like. From what I gather the fire button cable was in a clear covering. I looked all over for a similar type but due to lockdown I was limited to the shed. I did have some thin white cable and clear plastic for the fishpond, it worked a treat! As for the camera switch, a USB charging cable with a cord outer braid looked spot on (don’t tell the wife, she’s still looking for it).
I painted the camera switch and attached the usb cable
The fire button cable I also slotted in place
It just needs mounting on the stand and and the cabled gluing in place.
Enjoy
