Referring to Fig. 1-4, the utility model first embodiment, the mobile inductive switch of a kind of vibration mainly comprises: loam cake 1, lower cover 2, ball 3 and shell 4.Loam cake 1 is a metalwork, and its bottom face central authorities are the cone 11 to lower convexity, along its circumferential edge four cylinders 12 that distribute symmetrically.On the periphery of loam cake 1, be benchmark with the center line of cylinder 12, distribute symmetrically four cuboids or other body 13 except that cylinder, wherein one is contact rod 131 than the elder, remaining end face is the arc surface isometrical with shell 4.Lower cover 2 is a metalwork, and its top end face central authorities cone 21 for raising up is along its circumferential edge four cylinders 22 that distribute symmetrically.On the periphery of lower cover 2, be benchmark with the line of symmetry of two cylinders 22, distribute symmetrically four cuboids or other body 23 except that cylinder, wherein one is contact rod 231 than the elder, remaining end face is the arc surface isometrical with shell 4.

Cylinder

12,22 sizes on the upper and

lower covers

1,2 are identical, and size, the shape of contact rod 131,231 are identical.Ball 3 is the standard steel ball, and its size is determined by the space that upper and

lower covers

1,2 and

cylinder

12,22 form.Shell 4 is an insulation pipe, the upper and lower side groove 41 that

cuboid

13,23 matches, quantity is identical with upper and
