Aux Switches change - Savage out

All Change on the Aux panel.

The savage switches are no more, replaced with some robust stainless halo illuminated ones.

These have a 12v illumination, and two single pole switches - one normally open (NO) and one normally closed (NC), requiring a slightly different dimmer circuit.

Circuit

The load side now also needs a diode to prevent it being driven from the side light side of the circuit but letting it power the LED when on.

When off
  Side lights will light the switches dimly via the resistor
  Load is isolated from any illumination due to the diode

When on
  Side lights are disconnected from the switch on the NC side
  Load takes power from +ve
  Load feeds bright Illumination direct through the diode

(Assuming the switch is open before close)

The diode and resistor incorporated in these inline bundles attached to the load wire, all wrapped with shrink tubing once installed.

Before

Nothing wrong with the looks, just fell out with the switches themselves..

After

Retro dymo style labels instead of button logos.
The lighter socket is also gone, replaced with a 2x 5v USB unit (see footnote).

It was dark in the garage, meaning flash, meaning the colours where somewhat skewed - the switches illuminate blue dimly when lights are turned on, and brightly when the switch itself is turned on.

Before the Aux panel goes back in the radio needs a modification so it also transmits on bluetooth..

Update - The twin built in USB socket I found turned out to be no good. 

It's slightly over voltage, delivering ~5.4V and on power down sends some nasty spike through the USB lines. My Satnav especially didn't like it and would hard power off rather than just going to sleep as normal. Removed later.
