I'm using the V series of Carling rocker switches on my project. These are SPST with two lights, one independent and one dependent. Seven of these I will be using to trigger functions on the VPX, which just needs to ground out the switch pin on the VPX box.
The challenge comes in with the dependent lighting. This is how these look operating:
Want to ensure I have these wired up correctly before connecting them up and that I'll be able to utilize the dependent lighting as well as sending a switched ground to the VPX. The basic schematic for these look like this.
The VPX manual schematic looks like this.
The way I have it now is Positive connected to 8 which is then daisy chained to 2. Then a negative connected to 7. That method gives the correct lighting results as above and sends the volts across to 3 as expected.
Now for the switches using the VPX, if I put it the diode on pin 3 would that 'ground' it? Testing with a multimeter I put the black lead on pin 2 and the red at the end of the diode I hooked to pin 3. I verified that no current was coming across and then tested resistance. Unswitched it's open as expected and switch it's about 5 mega ohms. I'm new to messing with diodes so don't know what to make of all of it.
