Constant on or switched mod?

[obchristo]

Hello,
I have an Android based headunit in my 2005 Sequoia that connects to my house wifi network for updates. I also have a Dometic CFX that I plug into the back plug.

What I would like to do is install a switched circuit that would allow me to do 2 things:

1. Allow the circuit to function normally- turning on and off depending on the ignition.
2. Allow the circuit to stay on when I turn the ignition off.

I may install 2 different circuits and switches- one for each.

What do I need to do to make this happen and not destroy my electrical system?

Thanks,
Christo

Christo,
First the disclaimer - I work for Cradlepoint. We manufacture 4G LTE enabled Routers, that allows the Router to connect to the House WiFi as a "WiFi as WAN" for video & and Audio off-loading, we as support Ignition Sensing via our GPIO Cable and NetCloud Manager Software. ie example: Sheriff Officer pulls into Yard, Router converts from 4G LTE -to- WiFi as WAN, starts downloading the Video off the DVR at 5.0GHz, Officer turns off the Ignition, and completes his paperwork using the 2.4GHz connection. Next Officer exchanges position, fires up the Squad Car, and pulls out of the yard. Router converts back to 4G LTE connectivity. The router never re-boots. We have a Python SDK (Software Developers Kit) that allows a python coder, to write specific instructions for the Routers OS.

You could just hookup an adjustable Low Voltage Disconnect, leave it on all the time.. this is how my HAM radio and dash cam are wired up, have it shut off at like 12.4 which lets em run for a while after shutting down but nowhere near preventing me from starting..

My dashcam has wifi and it connects to home wifi, a python script is always running waiting for it to come onto the network.. then it grabs all new footage and puts it on my fileserver.. fun stuff.

If you dont mind manual operation. Simple solution is a SPDT toggle switch what selects between constant or switched power.
When you want that appliance constantly on, set the toggle to constant power, when you want the appliance to follow ignition, toggle the switch the opposite way.

That is EXACTLY what I am looking for. Thanks!

That is quite interesting but a bit more involved than what I need. Cook stuff! Thanks for the reply.

That may be a good addition to the SPDT toggle switch. Thanks!
