Looks like either could work, but I am hoping to have :
1. A simple ON OFF switch
2. All Top lights illuminated when Avionics Master is turned ON.
3. Lower light ON when that particular switch is on.
I think the SPDT switch may work. . . . But now the stupid question on how to wire it.
I plan to keep top lights (7-8) independent of bottom lights & circuit.
Also looks like I can wire 9 - 10 outside VPX logic as well & run those lights parallel to device? (So when device (ie, landing lights) turns ON, VPX will supply power to 9 along with power to landing lights, etc) 10 would be grounded.
So, now how to wire from VPX to 2,3,5,6????
Note: VPX activates the device without the load going through the switch. When switch is activated, it simply completes the circuit to ground to signal the VPX to actually send current to named device.
Thanks again!
