PURPOSE: To turn on a conventional emergency lamp by sensing tremor of earthquake by providing a switching device, an interface and vibration sensor in a box and also 100V input terminals and 100V output terminals in the switching' device. CONSTITUTION: By sensing earthquakes by sequentially installing a switching device 3, interface 4, vibration sensor 5 in this order in a box 1, a conventionally emergency lamp can be lighted even during an earthquake by forcibly interrupting 100V by the switching device. As a flow of 100V, 100V is connected to the 100V input terminal 2 before entering into 100V input terminal 2, and the current flows from the 100V output terminal 6 to the emergency lamp. As a result, the conventional emergency lamp can be turned while maintaining the its function as it is at the point of time when the tremor of the earthquake has been sensed. Also, only a small installation area is needed and the weight can be reduced. |
