"textContent": "A relay switch device installed on a transmission line of a battery pack to electrically connect or disconnect the battery pack and a load includes a relay assembly including: a contact member configured to apply a current to or release a current from the transmission line and a coil unit configured to function as an electromagnet for opening and closing the contact member; a control unit configured to supply or block a relay power applied to the coil unit; and an operating voltage sensing unit configured to sense an operating voltage applied to the coil unit from the control unit. The operating voltage sensing unit is further configured to transmit an error message to the control unit when the operating voltage is lower than a preset reference operating voltage or out of a preset normal operating voltage range.",
