Some aircraft distinguish between battery busbars (that can be disconnected from the battery) and hot battery bus bars that are connected directly to the battery, i.e. without any switching. This arrangement splits the battery bus with a direct connection (the ''hot'' battery bus), and a switched battery bus controlled by the battery switch.
