Abstract:
An acceleration detector for detecting acceleration exceeding a reference acceleration, said acceleration detector comprising:a fixed contact; a mass member having its first end in contact with said fixed contact; and an elastic member that has its first end in contact with a second end of said mass member, and presses said mass member to said fixed contact, wherein when said mass member, undergoing an inertial force exceeding a force of said elastic member, moves toward said elastic member, a conducting state between said mass member and said fixed contact is broken, wherein said mass member is composed of a conductive material, and said fixed contact comprises a plurality of fixed contacts, a first end of each of which makes contact with said mass member, and wherein when said mass member moves toward said elastic member, a conducting state between said plurality of fixed contacts via said mass member is broken.
