  • Patent number: 4559456
    Abstract: A portable type electric appliance powered by incorporated main and reserve batteries. The batteries are connected to an electric load selectively by means of a switching device including a main switch for connecting the main battery to the load and a subsidiary switch for connecting the reserve battery to the load. A lock locks the subsidiary switch in a disconnected position until the main switch is closed. Namely, the subsidiary switch can be closed only after the main switch is closed. Therefore, the main battery is always used prior to the reserve battery, and when the main battery is exhausted, the reserve battery remaining unexhausted is capable of taking over to operate the appliance without requiring immediate replacement of the main battery. Accordingly, the accidental interruption of the operation of the appliance can be avoided.
