Integrated Switching Device, and Battery Monitoring and Protecting System Including Integrated Switching Device

An integrated switching device in which a contactor unit which is capable of controlling a continuity state of an electric circuit, a blocking unit which is capable of cutting a contactor and blocking a current when abnormality is generated in the contactor or a current having a size exceeding a permitted current range of the contactor is generated, and a current measuring unit which is capable of measuring a current by using shunt resistor are integrated into one device, thereby performing various functions only with one device.
