after looking at the leds on the small pcb they are reversed on the same supply,
so its just the small tactile latch switch thats inverting the supply.
so do I get double pole latching.... so it flips the polarity..

Ok...should be able to do this with a alternate action DPDT PB switch.
But...either there is enough series resistance to keep the LEDs from blowing or there is a series resistor somewhere.
See attached. Each battery shown has 10 ohms series resistance.
