okay and so you can see here we've got the circuit for our lights and it's a pretty basic circuit we've got our two double-a batteries together they produce three volts the power is running through our switch we turn the switch on and the lights come on notice there's two resistors here those prevent the LEDs from drawing too much current and burning out and the switch opens and closes and lets the power go through we'll take a closer look at what is inside the switch
