Hi Stan;
One last bit of info....I'm planning on replacing the switch lantern bulbs with 24VDC BA9S (bayonet) white LED bulbs (I chose 24V because I can get 20 of them at a really decent price). The remainder of the switch bulbs are E10 screw base bulbs but the LED supplier is out of stock on those right now.
With that in mind, I'm thinking (hoping) the DC charger would be able to handle all the switches and their associated LED bulbs.
But I can always go back to the bridge rectifier approach.......
