The shock sensor, used for an automobile burglar alarm or a security system, makes an elastic rubber cap normally react upon various kinds of vibrations but not react upon an ultra low vibration caused by a passing automobile or an air flow. The shock sensor comprises a weight(8), fixed at a side of the cap(1), having an upper part closed and an lower part open; a vibration detection element(3) fixedly inserted into a lower part of the cap(1); a cover cap(2), of which diameter is less than that of the cap(1), forcefully covering the cap(1); a combining face(4) formed in the inner circumference of the cover cap(2); a wall face(6), also formed in the cover cap(2), producing a play gap(6); another cover(7) fixedly covering the cover cap(2); a groove(12) formed in the upper center of the weight(8); a combining hole(9) formed in the upper center of the cap(1). |
