The magnetic pole of the first magnets 41 can be opposite to the magnetic pole of the second magnet 42.
The first magnetic conductive block 43 can be magnetized by the first magnets 41 or the second magnet 42. Thus, the first magnetic conductive block 43 can couple the adjacent first magnets 41 or couple the second magnet 42 with the adjacent first magnet 41. The at least two the first magnets 41, the at least one second magnet 42, and the at least one first magnetic conductive block 43 can be arranged parallel to each other.

The second magnet members 50 can be coupled to a surface of the support portion 32 adjacent to the sliding member 10 and arranged apart (shown in FIG. 3). Each second magnet member 50 can face to the corresponding first magnet member 40. Each second magnet member 50 can include at least one third magnet 51, at least two fourth magnets 52, and at least one second magnetic conductive block 53. The magnetic pole of the third magnet 51 can be same as the magnetic pole of the second magnet 42. The magnetic pole of the fourth magnets 52 can be same as the magnetic pole of the first magnets 41. One of the at least one second magnetic conductive block 53 can be positioned between two adjacent fourth magnets 52. That is, the at least two fourth magnets 52 can be coupled to each other via the at least one second magnetic conductive block 53. The at least one third magnet 51 can be positioned at a side of the at least two fourth magnets 52 away from the second magnet 42. The at least one third magnet 51 can be directly coupled to the adjacent fourth magnet 52 or coupled to the adjacent first magnet 52 via another one of the at least one second magnetic conductive block 53 positioned therebetween.
The second magnetic conductive block 53 can be magnetized by the third magnet 51 or the fourth magnets 52. Thus, the second magnetic conductive block 53 can couple the adjacent fourth magnet 52 or couple the third magnet 51 with the adjacent fourth magnet 52. The at least two the fourth magnets 52, the at least one third magnet 51, and the at least one second magnetic conductive block 53 can be arranged parallel to each other. In at least one embodiment, a number of the at least one third magnets 51 can be one. A number of the at least two fourth magnets 52 can be two. A number of the at least one second magnetic conductive block 53 can be two. The two second magnetic conductive blocks 53 can be made of iron.

Another one of the second magnetic conductive blocks 53 can be sandwiched between the third magnet 51 and the adjacent fourth magnet 52.
The trigger member 60 can be coupled to the support portion 32 and positioned between the second magnet members 50. The second magnet members 50 can be symmetric relative to the trigger member 60. The trigger member 60 can include a trigger portion 61 positioned corresponding to the sliding member 10.

FIG. 4 illustrates that a magnetic pole of the second magnet 42 can be S-pole. A magnetic pole of the third magnet 51 can be S-pole. A magnetic pole of the first magnets 41 can be S-pole. A magnetic pole of the fourth magnets 52 can be N-pole. When the switch 103 is not triggered, the first magnets 41 can be respectively face to the corresponding fourth magnets 52. Thus, each first magnet member 40 and the corresponding second magnet member 50 can repel each other.
In assembly the electronic device 100, the first magnet members 40 can be coupled to the sliding member 10. The second magnet members 50 can the trigger member 60 can be coupled to the support member 30. The main body 11 of the sliding member 10 can be received in the receiving hole 102 of the housing 100. The extending portions 31 of the support member 30 can be coupled to the second fixing portions 23 of the fixing bracket 20.
When the switch 103 is not triggered, each first magnet member 40 and the corresponding second magnet member 50 can repel each other. The second magnet 42 and the fourth magnets 52 can opposite attract. The first magnets 41 and the third magnet 51 can opposite attract. Thus, a moving tendency between the first magnet members 40 can the second magnet members 50 can be produced. However, a frictional force between the sliding member 10 and the housing 101 can stop the moving tendency. Thus, the sliding member 10 can remain stable when the switch is not triggered.
When the switch to be triggered, the main body 11 of the sliding member 10 is pushed to move along the longitudinal direction of the receiving hole 102. FIG. 5 illustrates that the first magnet members 40 can move relative to the second magnet members 50 until the third magnet 51 faces the first magnet 41 away from the second magnet 41 and the second magnet 42 faces the fourth magnet 52 away from the third magnet 51. Thus, each first magnet member 40 can attract the corresponding second magnet member 50 to make the sliding member 10 to move towards the support member 30 and resist against the trigger portion 61. Thus, the switch 103 can be triggered.
When the sliding member 10 is pushed in opposite direction, the first magnets 41 can face the fourth magnets 52 again. The first magnet members 40 and the second magnet members 50 can repel again. Thus, the sliding member 10 can move away from the support member 30 to stop resisting against the trigger portion 61.
FIG. 6 illustrates a second embodiment of an electronic device (not shown) similar to the electronic device 100. Differences between the electronic device of the second embodiment and the electronic device 100 are illustrated below. A number of the first magnet 41 of each first magnet member 40 can be two. A number of the second magnet 42 can be three. Two second magnets 42 can be positioned at a side of the first magnets 41 and another one second magnets 42 can be positioned at an opposite side of the first magnets 41. A number of the first magnetic conductive block 43 can be four and respectively positioned between adjacent first magnets 41 and second magnets 42. A number of the third magnet 51 of each second magnet member 50 can be two. A number of the fourth magnet 52 can be three. Two fourth magnets 52 can be positioned at a side of the third magnets 51 and another one fourth magnet 52 can be positioned at an opposite side of the third magnets 51. A number of the second magnetic conductive block 53 can be four and respectively positioned between adjacent third magnets 51 and fourth magnets 52. When the switch 103 is not triggered, the first magnets 41 can face the two adjacent fourth magnets 52 and two adjacent second magnets 42 can face the third magnets 51 (shown in FIG. 6). FIG. 7 illustrates that when the sliding member 10 is pushed, an attract force between the first magnet member 40 and the second magnet member 50 can be larger than a repel force between the first magnet member 40 and the second magnet member 50. Thus, the first magnet member 40 can attract the second magnet member 50.
In at least one embodiment, the fixing bracket 20 can be omitted and then the support member 30 can be directly coupled to the housing 101.
In at least one embodiment, when the switch 103 is not triggered, an attract force between the first magnet members 40 and the second magnet members 50 can be less than a repel force between the first magnet members 40 and the second magnet members 50. When the switch 103 is triggered, an attract force between the first magnet members 40 and the second magnet members 50 can be larger than a repel force between the first magnet members 40 and the second magnet members 50.
