PROBLEM TO BE SOLVED: To provide an earthquake sensitive type electric cut-off device which is capable of preventing cutting-off operation from being generated, only by moving an instrument body, and facilitating its restoring operation after the operation. SOLUTION: This earthquake sensitive type electric cut-off device is constituted of a seismological device 11 which outputs a sensing signal by sensing shakings due to an earthquake, a control circuit 12 which outputs a control signal by inputting the sensing signal from the seismological device 11, a breaker 13 involving a contact which allows a conductive passage to be an off-condition by the control signal from the control circuit 12, whereas the breaker 13 is formed with cutting-off contacts 41 which are formed respectively at electric wirings 2 on this side of a receptacle 4 in a receptacle part 3, switching contact pieces 42 for switching the cutting-off contacts 41, a drive coil 43 which drives the switching contact pieces 42 as a result of a control signal from the control circuit 12 which is inputted, and a reset button 44 for returning, to an on state, from an off state such that the switching contact pieces 42 are detached from the contacts. |
