<p>PURPOSE:To obtain an acceleration response switch without any malfunction over a wide operating temperature range. CONSTITUTION:A conductive inertia ball 7 is housed in the closed container of an acceleration response switch 1, a vibration-damping liquid 9 such as alcohol and hydrogen carbide is injected, and a contact member 6 is fixed to the edge part of a lead terminal 3. The inertia ball 7 is normally located near the center and hence does not contact the contact member 6. When a vibration exceeding a specific value is given, the inertial ball 7 is rolled, contacts the contact member 6, and electrically connects a housing 5 and the contact member 6. Also, when the inertial ball 7 moves in an orbital along the side wall of the housing 5, the inertia ball 7 contacts the contacting part, its movement direction is changed, the movement is regulated by the vibration-damping liquid 9, the continuous contact between the contact member 6 and the inertia ball 7 is cut off, and the continuous output of ON signal is avoided. Also, even if the regulation effect of the vibration-damping liquid 9 is reduced, malfunction can be prevented in cooperation with the contacting part.</p> |
