I got first dibbs!
Much too tired to say much tonight, I must go back to the "real-world" tomorrow. After much trial and proto-types , I believe I have designed the complete solution for these cases.
For the switch I am using one I harvetsed from a DVD-player, but I bought some at Radio Shack , (Item#275-0004), today that were the same size, except much shorter and the specs say they are only rated for 50mA-12vdc, so at 5.5v that would be like 100mA right? I guess that would be ok, I would still rather find a better switch supplier.
For the anode-contact I have press-fit a section of Delrin, (acetal-plastic), and press-fit a solid-copper contact into the center. The wire from this contact will run to one side of the switch, the wire from the the other contact will run to the driver "+batt-side", the case would be grounded in this case. The copper contact may also be removed and I have counter-bored for a spring, if someone wanted to go with case-positive set-up.
I will probably be making a "run" next weekend of the ones for Murudai's barrels, and I will honor the original price, (these are a challenge and I like to live up to my word), unless I provide a switch, in which case is it cost that much more. "Future Sonar-Heat-Sink-modules- thingies" will likley cost more do to the time involved in making these.
BTW, these are set-up to take 2xcr123a's and are long enough for the "protected-rechargables"
