PROBLEM TO BE SOLVED: To automatically break electricity in a swinging condition when an earthquake occurs by fixing it to the inside of an outer box by connecting an electronic circuit having a vibration sensing unit in a line shape to a relay, and arranging a push button on the side end of the vibration sensing unit. SOLUTION: A relay 4 is installed on a switch 2 through an interlocking plate 3 on the inside of an outer box 1, and an electronic circuit 7 and a vibration sensing unit 5 are connected in a line shape to this relay 4, and a push button 6 is installed on the side end of the vibration sensing unit 5. At installing time, a power source side connecting inlet 10 is put below, and a switch 8 is turned on. Electricity of only its part can be automatically broken by swinging when an earthquake occurs, and the push button is arranged in the inward direction from the side end of the outer box, and is constituted so that a part of the push button is arranged inside from the side end of the vibration sensing unit, and whether or not this device is rightly actuated can be confirmed. Even when an electric current not less than a fixed quantity flows or leakage is caused, an ordinary breaking function can be exhibited. |
