PROBLEM TO BE SOLVED: To provide an apparatus aiming at reducing fires after an earthquake caused by electricity by automatically cutting off electricity at a time of a large earthquake.SOLUTION: The magnetic force earthquake sensor quickly cuts off electricity at a time of a large earthquake to eliminate earthquake fires. A magnetic force earthquake sensor 1 is put on a commercially available switch 2 so that, at a time of an earthquake of 6 to 7 gal, a sensor falls to activate a circuit breaker and quickly cut off electricity.SELECTED DRAWING: Figure 1 |
