When the first and second contact portions 38 and 44 are separated into two by the incision grooves 39 and 45, foreign matter is inserted into one of the first and second contact portions 38 and 44, or the shape thereof is changed. Even if the first and second fixed contacts 52 and 60 are not in contact with each other, the first and second fixed contacts 52 and 60 do not affect the other one of the first and second fixed contacts 52 and 60. It will not interfere with contact and energization.

5 is a view illustrating a state in which the fixed contact member of the switch structure having a sliding contact according to an embodiment of the present invention is coupled to the main body.

Referring to the drawings, the fixed contact member 50 includes a first fixed contact 52 and a second movable contact 40 which are positioned long along a line in which the first moving contact 36 moves on the inner surface of the main body 10. It includes a second fixed contact 60 is located along the line to be moved.

The first fixed contact 52 is in sliding contact with the first moving contact 36, and is positioned in the main body 10 to face the pair of first contact portions 38 provided at the first moving contact 36. It is provided in, and consists of a pair. Each of the first fixed contacts 52 is integrally formed with a first contact portion 54, a bent portion 56, a first fixed portion 57, and a first terminal portion 58 along the longitudinal direction thereof. . The first contact portion 54 is positioned to be exposed on the upper side of the inner side of the main body 10. The bent portion 56 is positioned below the first contact portion 54, and is bent in a direction away from the first moving contact 36 to be inserted into the side of the main body 10. The first fixing portion 57 is bent to be inserted in the bottom direction of the main body 10 at the lower portion of the bent portion 56. The first terminal portion 58 is positioned at the end of the first fixing portion 57 and extends to be exposed to the outside of the main body 10. As such, since the bent portion 56 of the first fixed contact 52 is inserted into the main body 10, the first contact portion 38 of the first moving contact 36, which is vertically moved inside the main body 10, has a first When positioned at the first contact portion 54 of the fixed contact 52, configured to be energized with the first contact portion 54, and positioned opposite to the bent portion 56 of the first fixed contact 52, It is comprised so that it may not be energized with the bending part 56.

The second fixed contact 60 is in sliding contact with the second moving contact 40, and is positioned in the main body 10 to face the pair of second contact portions 44 provided in the second moving contact 40. It is provided in, and consists of a pair. Each of the second fixed contacts 60 is integrally formed with the second contact portion 62, the second fixed portion 64, and the second terminal portion 66 along the longitudinal direction thereof. The second contact portion 62 is formed to extend downward from the upper side of the inner side of the main body 10 so as to be exposed to the inner side of the main body 10, and the upper end thereof is shown in FIG. 6 below, the first contact portion 54. It is provided at a position lower than). The second fixing part 64 is bent to be inserted in the bottom direction of the main body 10 at the bottom of the second contact part 62.

As such, the upper end of the second contact portion 62 of the second fixed contact 60 is provided at a lower position than the first contact portion 54 of the first fixed contact 52, so that the first moving contact 36 is provided in the first position. When in contact with the first contact 38 of the stationary contact 52, the second moving contact 40 is not in contact with the second contact 44 of the second stationary contact 60. And when the second movable contact 40 is in contact with the second contact portion 44 of the second fixed contact 60, the first movable contact 36 is the first contact 38 of the first fixed contact 52. It will not come in contact with.

Since the first and second fixed contacts 52 and 60 are simply formed integrally, the manufacturing cost is low, and when they are coupled to the main body 10, the first and second fixed contacts 52 and 60 are first and second. , 2 fixing parts (57, 64) is inserted into the main body 10, and simply coupled, there is an advantage that the assembly is easy.

Hereinafter, with reference to the accompanying drawings will be described a state in which the switch structure having a sliding contact according to an embodiment of the present invention operates.

6 is a view illustrating a state in which a switch is currently turned off because the loader of the switch structure having the sliding contact according to the preferred embodiment of the present invention is not pressed downward, and FIG. FIG. 6 is a view illustrating a first moving contact point and a first fixed contact point, and FIG. 6B illustrates a second moving contact point and a second fixed contact point.

First, referring to FIG. 6A, the first moving contact 36 is positioned above the main body 10 so that the first contact portion 38 of the first moving contact 36 is connected to the first fixed contact ( The first terminal portion 58 of the first fixed contact 52 is turned on while being in contact with the first contact portion 54 of the 52.

Subsequently, referring to FIG. 6B, the upper end of the second contact portion 62 of the second fixed contact 60 is provided at a position lower than the first contact portion 54 of the first fixed contact 52. The second contact portion 44 of the second movable contact 40 positioned on the same line as the first movable contact 36 is the second contact portion 62 of the second fixed contact 60 inside the main body 10. The second terminal portion 66 of the second fixed contact point 60 is turned off because it is not in contact with the contact point. That is, by the height difference of the 1st, 2nd contact parts 38 and 44 of the 1st, 2nd fixed contact points 52 and 60, the 1st moving contact 36 contacts the 1st contact part 38, and the 1st The fixed contact point 52 is turned on, and the second moving contact point 40 does not come into contact with the second contact part 44, so that the second fixed contact point 60 is turned off.

As such, when the loader 20 is positioned above the main body 10, the first fixed contact 52 is turned on and the second fixed contact 60 is turned off, so that the switch is turned off. And even if foreign matter is caught between the second movable contact 40 and the second fixed contact 60, and the second fixed contact 60 is turned on, since the first fixed contact 52 is on, the switch is turned off. By maintaining the state, there is an effect that the reliability of the switch is improved.

7 is a view showing that the switch of the switch structure having the sliding contact according to the preferred embodiment of the present invention is pressed downward, so that the switch is currently turned on (On), FIG. The first moving contact point and the first fixed contact point are shown, and FIG. 7B illustrates the second moving contact point and the second fixed contact point.

First, referring to FIG. 7A, when the first moving contact 36 is moved downward of the main body 10 by the pressure of the loader 20, the first contact portion of the first moving contact 36 is moved. 38 is slid downward along the first contact portion 54 of the first stationary contact 52 and then positioned on the inner surface of the body 10. At this time, since the first moving contact 36 is not in contact with the first fixed contact 52, the first terminal portion 58 of the first fixed contact 52 is turned off.
