New sub-panel

This for the actual or aspiring electrical engineers!...  

I have a new Si-Tek AIS transceiver to wire in for Volant, to transmit the boat's position for safety.  Among its various connections to equipment on the boat, it needs a power source that should be switched and fused.  The present electrical distribution panel is fully populated, with no empty switch positions available.  I cannot find a distributor for any sort of remotely similar auxiliary panel that would not look completely out of place.  So I decided to try to fabricate a closely matching 6-switch sub-panel, with the expert help from a good friend.  This will provide extra switches for accessories that are constantly powered now, like chart plotter, VHF radio, and stereo, to make it simpler to turn them on and less likely we forget to turn them off.  

Here is my drawing of the new sub-panel and a representation of how it will look, complete with French and English labels, as is done on the current panel.  The switch at the bottom is wired to the nuclear flux capacitor to provide cross-dimensional speed.  [Ummm, well, no -- it's not technology proven in "Back to the Future".  It's a spare actually, and gets its label from a running joke we had on Mercedes!]
