りり放す必要が生じる。BACKGROUND ART Conventionally, a normal relay has been used to disconnect a power source and a load, and electric power is consumed to move the relay in the L direction. Electronic switches can be used in place of relays, but electronic switches have a current limit, so they cannot be used when large currents must be crossed, and voltage drop also becomes a problem. In addition, in electrical equipment that uses batteries as a power source, the output voltage decreases over time, and if used continuously, the operation of the equipment may become unstable, and in the case of secondary batteries, the life of the battery may decrease. Otherwise, it becomes necessary to remove the battery and the device.

Part 17. The capacitor is charged in the first switching mode of the J exchanger switch, and has two stable states, one of which is loaded and supplies power, and the other stable state is where power is supplied to the load. The second switching of the IJ11 decoupling switch enters the stable state of one of the latching relays, and the detection signal from the IJjJ voltage saving/u l!!l path is detected. The special imitation is that the other latching relay of +jfJ enters the stable state at
