I am trying to trigger +12v going to a multi-view backup camera to signal it to change views when I press a toggle switch. The problem I face is that the toggle switch is NC and the 12v drops OFF when the button is pressed. I remember using 2 relays in the past to get around this situation but I forget how to make this work and how to wire it. I would like to use as small of a setup as possible and the small backup camera is rated at 12v <70mA so I would like to use as small of a setup as possible. Any help would be greatly appreciated.
