Abstract :
This paper proposes a vibrational circuit breaker which cuts an electric and/or electronic circuit by vibration of acceleration more than a certain value. This structure consists of a fixed magnet, a moving magnet, and a fixed part of two ferromagnets/magnet. It works from on-state to off-state when the two ferromagnets separate. This vibrational circuit breaker has advantages: auto-detection, no battery, and simple structure.
