Can I use this switch for ON/OFF and 5V DC? : r/AskElectronics

Will this wiring circuit work? I wish to use one rocker switch to turn on/ off the two LED bulbs, which are powered by two individual 12V batteries. (Sorry for the poor wiring

Want to use this Ecig battery and charging circuit, but don't know how to isolate the pressure switch. : r/AskElectronics

Could someone help me figure out what IC that is? It's a DC/DC converter from a PoE Board of a Switch. Input is 55V and output is either 3.3V or 5V.

Is such a wiring configuration possible? How should I consider current draw of components when choosing a power supply? : r/AskElectronics
