Problems solved by technology

Chinese patent ZL92216616.1 discloses a "rolling contact switch" which includes upper and lower conductive contact plates and conductive balls. When it needs to be turned on, its rolling is limited to a certain extent, which reduces the sensitivity; (2) The tilt position of the switch when it is turned on is related to the depth of the concave of the lower conductive contact plate, and the top and bottom ends of the ball must be in contact with the upper and lower conductive contacts respectively The plate contact can be turned on, and the precision of manufacturing, processing and assembly is high; (3) In the non-inclined position, a large shaking will make the ball leave the recess of the lower conductive contact plate and make the switch conduct, which is likely to cause misoperation ; (4) The connection relationship of the parts is complicated, which brings inconvenience to the production, processing and assembly

Embodiment 1

[0021] figure 1 with figure 2 Shown is one of the embodiments of the present invention, including a conductive upper cover 1 , a conductive base 2 , a conductive rolling body 3 and an insulator 4 . The inner surface of the conductive upper cover 1 is a plane, and the conductive base 2 is a shell structure with a bottom surface 5 and an inner surface 6, and the bottom surface 5 is a plane. The conductive upper cover 1 is covered on the top of the opening of the conductive base 2, and the insulator 4 is arranged at the connection between the two. The conductive upper cover 1, the conductive base 2 and the insulator 3 form a closed cavity, and the conductive upper cover 1 and the conductive base 2 are the positive and negative electrodes of the entire switching device. ; The conductive rolling body 3 is a conductive ball, which is set in the cavity and can roll. Such as figure 1 As shown, when in the horizontal position, the conductive rolling element 3 stays on the bottom s...

Embodiment 2

[0023] image 3 with Figure 4 Shown is the second embodiment of the present invention, which is different from the first embodiment in that: the inner surface of the conductive upper cover 1 is a concave surface, and the bottom end of the conductive upper cover 1 has an outwardly protruding convex edge 7, facing the void. There is a bevel transition in the cavity to reduce the wear between the conductive rolling elements. The edge of the top of the conductive base 2 has a protruding concave edge 8, the convex edge 7 of the conductive upper cover is arranged in the concave edge 8 of the conductive base, and the insulator 4 is arranged between the contact surface of the convex edge 7 and the concave edge 8. Such as image 3 As shown, when in the horizontal position, the conductive rolling element 3 stays on the bottom surface 5 of the conductive base and only contacts the conductive base, and does not contact the conductive upper cover 1 (there is a gap between the top of the...

Embodiment 3

[0025] Figure 5 Shown in Fig. 6 is the third embodiment of the present invention, which is different from the first embodiment in that: the inner surface of the conductive upper cover 1 is a concave surface, and the inner surface of the conductive base in the cavity is provided with a conductive inner collar 9 ; The insulator 4 is located at the contact connection between the bottom edge of the conductive upper cover 1 and the conductive base 2 and the conductive inner collar 9 . Such as Figure 5 As shown, when in the horizontal position, the conductive rolling element 3 stays on the bottom surface 5 of the conductive base and only contacts the conductive base, and does not contact the conductive upper cover 1 (there is a gap between the top of the conductive rolling element 3 and the conductive upper cover 1 ), at this time, there is no electricity between the conductive upper cover 1 and the conductive base 2, so the whole device is in a non-conductive disconnected state....
