I think your current connection leading from the main LED to the LED (-) of the switch has to go to the NO1 terminal of the switch instead. The resistor for the switch has to be moved between the NO1 and the LED (+) of the switch. And you also need a connection from the negative coming from the battery pack to the LED (-) of the switch. I'm no expert, but I'm quite sure that it should work after you add/change these connections.
Yep Racona, spot on....... +1
I think what you just described actually works with a buck puck, but I'm no expert. It just seems absolutely convoluted
Any chance you could re-do your diagram with those changes Kal-El? Would be great for future reference for others wanting a latching av switch too..... +1
