Single axis vibration switch

Abstract

A kind of single axes type oscillation switch includes a shell unit, a free element, a electrode, and a elastic conductor, the shell unit includes a first shell, and the second shell which combines the first shell to cover and bound a containing space, the first shell is conductor, the second shell is insulator, the free element is set in the containing space and near the first shell, the electrode is separated from the first shell and passes through the second shell, the elastic conductor is set in the containing space and between the free element and electrode, and electric conducted with the first shell, when there is oscillation, the free element can push the elastic conductor to contact electrode, so the electrode, elastic conductor, the first shell are electric connected to form a conductive path.

Description

【Technical field】 [0001] The invention relates to a vibration switch, in particular to a single-axis vibration switch. 【Background technique】 [0002] Referring to Figures 1 and 2, it is the existing Chinese Taiwan No. 181432 "uniaxial vibration switch" new patent. This uniaxial vibration switch includes a housing unit 10, an elastic element 20, an electrode 30, and a free part 40. [0003] The casing unit 10 includes a first casing 11 surrounding an axis I, and a second casing 12 combined with the first casing 11 to form a chamber 13 . [0004] The first housing 11 is an electrical conductor and has a first inner side 111 located in the chamber 13 and facing the second housing 12 , a first outer side 112 opposite to the first inner side 111 , and a first electrode 113 protruding from the first outer surface 112 . [0005] The second housing 12 has a second inner side 121 located in the chamber 13 and facing the first inner side 111, a second outer side 122 opposite to th...

Problems solved by technology

[0010] However, in actual operation, the design of the above-mentioned uniaxial vibration switch still has shortcomings, so that improvement is necessary to make the overall quality better and more accurate. Its shortcomings can be found from Figure 2. When it is in the conduction state, Since the free piece 40 is not fixedly connected to the elastic element 20, and the elastic element 20 is not fixedly connected to the metal sheet 123, so the entire conducting path is through the contact between the electrode 30 and the free piece 40, the contact between the free piece 40 and the elastic The contact of the element 20, the contact of the elastic element 20 and the metal sheet 123 is completed, and the use state of conducting through three contact points 101 is formed, and since it is through multiple contact points 101 above a single contact point The conduction state is completed, so on the one hand, there are disadvantages of unstable signals and increased uncertainties during the conduction process, and on the other hand, because there are many conduction conditions, three contact points 101 need to be satisfied at the same time to form conduction. The disadvantage of slow response to vibration
