Zusammenfassung:	An alarm device for switch box having a vocal massage sensing function is provided to prevent an accident due to an electric shock by installing a first sensor for performing a first warning operation and a second sensor for performing a second warning operation in a switch box. A first sensor(20) generates a signal according to an opening state or a closing state of a door and transmits the generated signal. A second sensor(30) reacts with electric field generated in a current-conducting state of a switch box, generates a signal, and transmits the generated signal. An input unit(40) receives the signals from the first and second sensors. A microprocessor(50) generates a control signal according to the opening state or the closing state of the door and a reacting state with the electric field. A voice generation unit(80) outputs a predetermined warning message to a speaker(S) according to the control signal of the microprocessor.
