I have one switch and: 1 9v battery going to LEDs, another 9v battery attached to another group of leds, another 9v battery connected to an arduino, 3x AA batteries attached to servos and another 3x AA batteries attached to a different set of servos. I want to turn on and off all these different power sources with a switch, would I have to connect all of the batteries' positives to the positive end of the switch and all the grounds to the negative on the switch? Would this work? Or would this cause a short?
Thank
