Map Light Wiring; Passive Audio Mixer
Continuing with light wiring, I put this little ON-OFF switch directly beside the map light. It will obviously turn the light on and off.
Here you can see how tiny this switch is compare to the others. This switch is only going to see about .25 amps max though. After I soldered this I realized that it will make the panel a little more of a pain to remove because the LED light pulls out of the panel from the front and the switch from the back. The light works perfectly. I actually wired it to one of my dimmers. The only things in the panel that are going to be dimmable are the map light and the nu-lites. Everything else has photocells that dim the units automatically *or* they are manually dimmed via software (such as the Dynons).
This is something I came up with. We'll see how well it works. I've been testing my audio alerts using various resisters. Basically what I did was crimped some pins onto some resistors then soldered a wire to them all together and soldered this wire to them. This will give me a little passive audio mixer into the intercom. The wire coming out of the d-sub will go to the intercom. The Dynon EMS+EFIS and COM radio will feed into three of the pins. The other pins are for future use. I sort of randomly chose the resistors to use based on my completely unscientific testing.
For my future reference here are the resistors I used. I left three of the pins open in case I want to go back in there and add a different size resistor.
