Ball switch

Abstract

The invention discloses a ball bearing switch which comprises a conductive shell, two ball bearings that are arranged inside the conductive shell and can conduct electricity, at least one insulating cover body that is arranged in the conductive shell and leads the ball bearings to be limited, and at least one terminal. The conductive shell comprises an internal circumference surface which is arranged around a central axis and forms a containing hole, and the containing hole is provided with first aperture and second aperture that are intersectant with each other; the terminal is inserted and fixed in the insulating cover body along the central axis as well as is provided with a contacting ring surface arranged in the containing hole; wherein, the first aperture is greater than the sum of the diameter of the ball bearings, the second aperture is greater than the diameter of the ball bearings, and the diameter of the ball bearings is longer than the distance between the contacting ring surface of the terminal and the internal circumference surface. In this way, the ball bearing switch has the using characteristics of effectively improving the success rate of conduction and improving the quality.

Description

technical field [0001] The invention relates to a switch, in particular to a ball switch used for circuit board signal conversion. Background technique [0002] Such as figure 1 As shown, the electronic tilt switch (electrical tilt switch) 10 of U.S. Patent No. 5,332,876 has a conductive housing 11, a large ball 12 and a small ball 13 respectively located in the conductive housing 11, and one closes the conductive housing A cover 14 of the opening 111 of the body 11, an electronic connector 15 inserted into the cover 14 and extending into the conductive housing 11, and a terminal fixed to the closed end 112 of the conductive housing 11 16. [0003] When in use, when the electronic tilt switch 10 is tilted, the small ball 13 rolls in contact with the electronic connector 15 and a first contact point 17 is generated between the two, and the large ball 12 sticks to the small ball 13 and between the two The second contact point 18 is generated, and the large ball 12 sticks to...

Problems solved by technology

[0004] Although the above-mentioned electronic tilt switch 10 can generate a signal conversion function through conduction and non-conduction, and it is intended to give the small ball 13 the power of the large ball 12 Gravity improves the success rate of contact conduction, but because the conduction signal must be generated under the simultaneous existence of the first contact point 17, the second contact point 18 and the third contact point 19, in fact there is still conduction The failure rate and defect rate are high, resulting in the lack of poor quality

[0005] In addition, the electronic tilt switch of US Patent No. 5,209,343 also has a high conduction failure rate, resulting in the lack of poor quality
