In case there are some out there considering strobe power supplies for
their RV10, here are some diagrams that may be of interest.
Here is (hopefully) a link to a page of the instructions for the old
CreativAir Avi-pak strobe power supply. I don't think these are sold
any longer but I'm sure a number of older RV10s have them.

Here is a link to a page from the non-aviation supply from Nova
Electronics where the switch is in some kind of control circuit.

Given the typical locations in the RV10, Wiring the main power line to a
power bus location that is local to the battery seems preferable to
running the same power line up to the panel and back.

My 'old-timers disease' must be kicking in. When I looked at your diagram, for
some reason that symbol seemed backwards. But I looked at my own diagrams and
they are the same as yours!
