My friend has a garage door that when opens turns on a floodlight.

He know wants it to turn on another light in the garage as well as the floodlight.

The problem is this garage light is already on a plate switch, if the garage light was simply connected to the control panel then the plate switch would then operate the flood light as well, this needs to be avoided. (see pic below)

Does anyone have a simple solution? Is there anyway to allow the line current only to flow from the panel and stop the back flow of current to the panel from the plate switch?
