Need Help with OLJK two battery switch

*How big of a cap would we need to survive a 1sec loss of power with a 500ma load allowing for a 1VDC drop? Constant current discharge of a capacitor (will be close enough)... C = t . i / deltaV = 1 . 0.5 / 1 = 0.5 F Easily doable with today's supercapacitors. But as I pointed out earlier, mechanical switch issues usually happen over time frames of 10's of ms. Not 1 sec. And why do anything if it is not really needed. Darryl
