I was wondering if this would work as a visual indicator if a switch was opened for a PNP transistor at the base. Basically, as long as the switch is closed, then I don't want the led on, but as soon as the switch is opened, then I wanted to have an external battery supplying the power to indicate the switch is opened. There are more than 1 switch at various locations, but any one of those would flip a relay and I wanted to have 1 switch be the initial indicator for all switches. Appreciate the advice an help.
