A "bright" idea: illuminated window switches ** Important order info added **
#137
I have one of the bezel's and hoping to find a switch set at some point.

Paul covered most of the basics, so I will just post a couple comments, and then move on to answering any specific questions. First, I want to comment that these are truly state-of-the art guts. Neither Paul or I was willing to compromise any part of construction for these, and while they seem simple, it is the result of several months of work. The illumination system is passive, and very durable. It shouldn't break or fail under normal use (it is susceptible to a blow from a sharp object - like if you stabbed the panel with a screw driver). There are no transformers or EL membranes used, so no buzzing will be introduced into the cabin or into radio transmission. The switches used are not common, or even commonly available. We have had to go through extensive drawing revisions to earn the opportunity to use them. Again, these units are designed to not fail, and have been tested into the millions of operations without failure. In short, our panels are truly lifetime switches, and will not need to be replaced if cared for properly.
It is important to note that these switches DO NOT operate the windows directly. They are a very low-current signal type switch, which again improves the lifetime of the switch contacts. Our switch panels have been designed to interface with DEI products 530T and 529T. They could also be used in a "budget" configuration with several relays instead. I will be providing a plug-and-play harness for connection with the DEI modules, and also installation/circuit notes if you choose to use relays or a different method of controlling the windows. I think the advantages of using the DEI units are very apparent, and assume that most people will want to go in that direction.
Using the DEI units gives you 1-touch operation for any year 928. It also gives you the option to tie the windows in with an alarm system or key-less entry system. You can have the windows roll up when the alarm is armed or when it is set-off. You can also add a vent position, which will crack the windows to allow circulation. Another reason we chose to use DEI over making our own module is that they are cheap, readily available, and tested in tens of thousands of alarm installations across the world for almost the last decade. They are very reliable, and most electronics professionals and even mechanics are familiar with their operation and should be able to quickly diagnose any problems you may have with them. They are a stock item at most electronics shops, so if you are ever on a road trip, and for some reason a unit fails, you should have to drive very far to get an emergency replacement if necessary.

How hard would this concept be to work out with today's modern touchscreen technology for the console switches. I was also thinking of a way to use touchscreen with proper controls electronics connected to it for the HVAC controls. Since so many people have had issues with the HVAC units it would be great to have a modern interpretation using touchscreen to control HVAC as well.
