FatShark Power Switch : On/Off Switch for your Fatsharks

FatShark Dominator Power Switch Mod

I love my FatShark Dominator V3. One thing I don’t like about them is fumbling around to plug in the power cable. I’ve always wanted to add a Fatshark power switch but never got around to doing it until now. Adding a power switch makes them so much more enjoyable to use.

FatShark Power Switch Modification

Open the cover. Remove the two screws and loosen the center screw. Remove the power board module and unplug the wire harness.

Use a 5/8″ drill bit to drill a hole in the cover. On the inside of the cover there is a circle injection mark. Use that circle to mark where to drill. If you put it dead center, the switch will line up perfectly inside the goggles.

Cut the tab on the back of the plug.

  1. Red – 40mm
  2. Black – 57mm
  3. Green – 58mm

Trim the tabs on the back of the button so it will fit inside the goggles. Put the switch through the hole of the cover.

Solder up the wires like this. This wiring diagram is setup to have the LED on the power switch to turn on only when the power is on. This schematic is for this power button.

Note the green wire is soldered to the center tab and the bottom tab.

Put everything back in the goggles in reverse order and you’re done. Now you can leave your goggle battery plugged in and it will only turn on when you hit the Fatshark power switch. The LED will be lit when the power is on. Go fly!
