Description

Gear change-over switch with two switches and one switch

Technical Field

The utility model relates to the field of switches, in particular to a two-switch one-switch gear change-over switch.

Background

Traditional mechanical key switch all is electrically conductive through the spring contact, thereby has increaseed the contact link of metalwork and has increaseed contact resistance, makes the product generate heat easily under the circular telegram condition of product itself, and the inside contact spring of product is blown easily under the condition that the electric current is bigger than normal.

In addition, the switch in the prior art adopts an on-off operation mode, and the switch can only adjust one state, cannot be used for switching the types of mechanical key switches, and obviously cannot meet the requirements of people on a gear change-over switch.

Therefore, a two-switch one-switch gear change-over switch becomes a problem to be solved urgently in the whole society.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems, the technical scheme provided by the utility model is as follows: the utility model provides a gear change over switch of two switches one switch, includes button, upper cover, swiveling wheel, rotatory contact cap, spring and lower cover, on cover and be provided with first pin, second pin and third pin, first pin, second pin and third pin and rotatory contact cap between the cooperation switch on.

Furthermore, the lower part of the button is in a toothed structure, and the top of the rotating wheel is provided with a toothed structure matched with the lower part of the button.

Further, the bottom of swiveling wheel is provided with two sets of spliced poles, be provided with spread groove and the connecting hole with the spliced pole adaptation on the rotatory contact cap.

Further, the bottom of lower cover is provided with the fixed column, and the bottom setting of spring is in the outside of fixed column.

Further, the top of the spring is arranged on the inner side of the button, and the top of the spring is in contact with the button.

Further, first pin, second pin and third pin are five metals contact foot, first pin, second pin setting are in one side of button, the third pin sets up the opposite side at the button.

Compared with the prior art, the utility model advantage lies in: the utility model can effectively realize the switching among different gear switches and meet the requirements of people on the switching of the gear switches; and in the operation process, the internal structure can effectively prevent the internal spring from being burnt out, the practicability is strong, the operation is simple, and the operation is convenient.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present invention will be described in detail with reference to the accompanying drawings.

The utility model provides a two-switch one-switch gear change-over switch, which comprises a button 1, an upper cover 2, a rotating wheel 3, a rotating contact cap 4, a spring 5 and a lower cover 6, and is characterized in that: the upper cover 2 is provided with a first pin 7, a second pin 8 and a third pin 9, and the first pin 7, the second pin 8 and the third pin 9 are communicated with the rotary contact cap 4 in a matching manner.

The lower part of the button 1 is in a tooth-shaped structure, and the top of the rotating wheel 3 is provided with a tooth-shaped structure matched with the lower part of the button 1. The bottom of swiveling wheel 3 is provided with two sets of spliced poles 10, be provided with on the rotatory contact cap 4 with spliced pole 10 adaptation's spread groove 11 and connecting hole 12. The bottom of lower cover 6 is provided with fixed column 13, and the bottom setting of spring 5 is in the outside of fixed column 13. The top of the spring 5 is arranged on the inner side of the button 1 and is contacted with the top. First pin 7, second pin 8 and third pin 9 are five metals contact foot, first pin 7, second pin 8 set up the one side at button 1, third pin 9 sets up the opposite side at button 1.

The specific embodiment of the utility model is as follows: when the gear shifting switch is used, the upper button 1 is pressed, the button 1 moves downwards, the rotating wheel 3 is driven to rotate, the rotating contact cap 4 is driven to shift and jump to rotate so as to adjust the gear, punishment is carried out for one time, the third pin 9, the first pin 1 and two ends of the rotating contact cap 4 are triggered to be electrified, triggering is carried out for the second time, and the third pin 9, the second pin 8 and the rotating contact cap 4 are triggered to be electrified, so that the gear shifting switch is realized, the switch switching process is finished, and different requirements of people are met. When the trigger is triggered for three times, the third pin 9, the first pin 7 and the second pin 8 are disconnected from a circuit neutral gear, and the operation is performed in a circulating mode sequentially.

The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the utility model as defined by the appended claims.
