[0036] The utility model is further described in detail below with reference to the accompanying drawings:

[0037] like Figure 1 and Figure 2 As shown, this embodiment discloses a position switch touch device, including a mounting member; a pressing member, slidably mounted on one side of the mounting member, the pressing member is connected to a guide rod 2, and the end of the guide rod 2 passes through the mounting member and is fixedly connected to a touch member; an elastic member, sleeved on the outside of the guide rod 2 and located between the pressing member and the touch member, providing displacement power for the guide rod 2; a rolling member, fixedly connected to the end of the guide rod 2, when the rolling member is pressed, drives the guide rod 2 to make the touch member contact with the micro switch 6. Figure 1 , Figure 3 and Figure 4 As shown, the mounting piece is mounted on the bottom of the trolley room partition 8 by connecting the standard piece 5, wherein the left end of the top of the trolley room partition 8 is the test position, and the right end of the top of the trolley room partition 8 is the working position. A touch device is installed at both ends of the trolley room partition 8. When the circuit breaker is in the test position, the bottom of the circuit breaker presses the rolling piece at the left end of the trolley room partition 8, and the rolling piece at the left end is squeezed by the gravity of the circuit breaker to drive the guide rod 2 to move downward. During the displacement process, the pressing piece is driven to slide downward on the mounting piece at the same time. During the downward displacement of the guide rod 2, the touch piece at the end of the guide rod 2 is directly contacted with the micro switch 6. The micro switch 6 obtains the position signal of the circuit breaker being in the test position, and sends the signal to the control system. The control system is controlled to obtain the signal that the circuit breaker is in the test position.

[0038] Similarly, when the circuit breaker moves from the test position to the working position, the bottom of the circuit breaker presses the rolling element at the right end of the trolley chamber partition 8, and the rolling element at the right end drives the touch element at the end of the guide rod 2 to directly contact the micro switch 6. The micro switch 6 obtains the signal that the circuit breaker is in the working position and sends the signal to the control system, thereby obtaining the signal that the circuit breaker is in the working position.

[0039] Furthermore, the pressing member is a pressing plate 9, which is slidably mounted in the middle of one side of the mounting member, and a mounting hole is provided on the pressing plate 9, in which the guide rod 2 is mounted, and the end thereof passes through the mounting member and is fixedly connected with a touch member. Specifically, during the downward movement of the guide rod 2, the guide rod 2 drives the pressing plate 9 to move downward as well, and during the downward movement, the pressing plate 9 compresses the elastic member, and after the circuit breaker moves away from the test position, the compressed elastic member can provide displacement power for the rolling member, thereby realizing the resetting of the rolling member and ensuring reliable operation.

[0040] In this embodiment, the contact member is a contact plate 7. Specifically, the contact plate 7 is a structure with one end open and the other end blocked, the length of the contact plate 7 is equal to the width of the pressing member, and the contact plate 7 has an open end away from the side of the pressing member.

[0041] In this embodiment, a limit plate 10 is further provided on one side of the mounting member, and the end of the guide rod 2 passes through the limit plate 10 and is fixedly connected to the touch member; one end of the elastic member is fixedly connected to the pressing member, and the other end is fixedly connected to the limit plate 10. Specifically, the elastic member is a spring 3, and the setting of the limit plate 10 can prevent the contact plate 7 from damaging the micro switch 6.

[0042] In this embodiment, the mounting member is a mounting plate 4, the mounting plate 4 is a T-shaped structure, the pressing member is slidably mounted on one side of the vertical end of the mounting plate 4, and the rolling member is located at the top of the vertical end of the mounting plate 4. Specifically, the rolling member is a roller 1, and a movable groove is opened on the horizontal end of the mounting plate 4, the movable groove is located in the middle of the mounting plate 4, and the roller 1 is located in the movable groove.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
