Document Type and Number:
Japanese Patent JP2016006782
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vibration-sensitive electric-conduction breaker that is configured in a simple structure and actuated immediately upon vibration of an earthquake, and can cut off a breaker such as a distribution board, a cabinet panel or the like under energization through the actuation.SOLUTION: A magnet is detachably provided to the inside of the upper end of a cylindrical casing which has a proper length and blocked at the lower end portion thereof. The upper end portion of the casing is provided with a suspending member for suspending the casing from an upward facing knob under ON-state of a turn switch of a breaker.
