Problems solved by technology

[0009] Although the ball switch 1 can utilize the reduced-diameter aforementioned slot 14 to limit the range of light communication between the emitting head 173 and the receiving head 183, because the aforementioned slot 14 is a long strip channel that communicates with the receiving slot 13 , so in fact, it is still unable to effectively limit the light scattering of the spherical emitting head 173 and the receiving head 183, causing the light emitted by the emitting head 173 to easily scatter from the top of the aforementioned slot 14 and cause light refraction to cause communication. effect, relatively there is a defect that is more prone to misoperation
[0010] This shows that the above-mentioned existing ball switch obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have an appropriate structure to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve

Abstract

The invention relates to a ball bearing switch that comprises a base, a emitter, a receiver, a ball bearing, and a outer cover which covers said subassembly. The base includes a bottom block, a center block, a first bearing block, a second bearing block are extended from the bottom block, a containing groove which is set on the center block to contain the ball bearing, a emitting head which is set on the first bearing block and the second bearing block to bear the emitter, a first bearing surface, a second bearing surface of a receiving head, and the first channel, the second channel which link the two bearing surface. The outer cover includes a first pressing block, a second pressing block and a stopper which prevents light beam to be reflected which are pressed on the emitter and the receiver. So, the invention can prevent light beam to be reflected and scattered effectively, and without fault operation.

Description

technical field [0001] The invention relates to a switch, in particular to a ball switch which utilizes a transmitter and a receiver to achieve the opening and closing action, which can effectively prevent light scattering and refraction, and prevent malfunction. Background technique [0002] Please refer to FIG. 1 and FIG. 2 . FIG. 1 is an exploded perspective view of a conventional ball switch, and FIG. 2 is a cross-sectional view of a combined structure of the conventional ball switch. A kind of existing ball switch 1, comprises an insulating shell 10, a ball 16, an infrared emitter 17, a photoelectric switch 18, and an insulating outer cover 19; Wherein: [0003] The casing 10 has two placement grooves 11 arranged from a stepped top surface 101 toward a bottom surface 102 and spaced apart from each other, respectively communicating with each placement groove 11 and two through holes 12 of the bottom surface 102, one from the top surface 101 The accommodating groove 13, ...
