My guess is that printed circuit board is used for numerous converter applications and is not utiized in the configuration you are purchasing. There probably is a model where the converter can be activated via an ignition key (such as in a golf cart) but that model does not appear to be for that use. If you look at the bottom of the board when you receive it the two "key" holes are probably bridged together.
