Abstract
The utility model relates to a reset piano-key switch, and belongs to the technical field of electric switches. The reset piano-key switch comprises an insulating body. The insulating body is provided with a supporting shaft, a rocker component which is rotatingly connected with the supporting shaft, a switch board which is connected with the rocker component, a fixed contact point, and a movable contact point. An elastic piece is disposed between the switch board and the insulating body and used for enabling the switch board to be reset The reset switch is delicate in design, simple in structure, and high in stability.
Description
Technical field
The utility model relates to a kind of keyboard switch that resets, and belongs to the electric switch technical field.
Background technology
Reset switch, by each operation of opening and closing, can realize that button returns to origin-location, and in order to realize this function, the resetting device of existing reset switch is generally all more complicated, and the parts of employing are also more, and cost of manufacture is high, less stable.
The utility model content
The technical problems to be solved in the utility model is, proposes a kind of simple in structure, stability is high, cost is lower keyboard switch that resets.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of keyboard switch that resets, comprise insulating body, described insulating body is provided with back shaft, the seesaw member be rotationally connected with back shaft, switchboard, fixed contact and the moving contact be connected with the seesaw member, between described switchboard and described insulating body, is provided with the flexure strip that switchboard is resetted.
Improvement of the technical scheme is: described switchboard have two and structure identical.
Further improvement in the technical proposal is: described flexure strip is torsion spring.
Further improving again of technique scheme is: described torsion spring one end is connected with the back side of described switchboard, and the other end is fixedly connected with described insulating body.
The beneficial effects of the utility model are as follows:
The keyboard switch that resets of the present utility model just arranges this simple part of torsion spring between switchboard and insulating body, can realize automatically reseting of when the end that torsion spring is arranged of seesaw member unclamps switch, the resetting device of the various complexity compared to existing technology, resetting device of the present utility model is simpler, stability is high, and cost is lower.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, to of the present utility model, be described further.
Fig. 1 is the structural representation of the utility model embodiment mono-.
Fig. 2 is the front view of Fig. 1.
Fig. 3 is the structural representation of torsion spring in Fig. 1.
Fig. 4 is the structural representation of the utility model embodiment bis-.
Embodiment
The a kind of of the present embodiment resets keyboard switch as depicted in figs. 1 and 2, comprise insulating body 1, switchboard 4, fixed contact and moving contact that described insulating body 1 is provided with back shaft 2, the seesaw member 3 be rotationally connected with back shaft 2, is connected with seesaw member 3, be provided with the torsion spring as shown in Figure 35 that switchboard 4 is resetted between described switchboard 4 and described insulating body 1, torsion spring 5 one ends are fixedly connected with the back side of switchboard 2, and the other end is fixedly connected with insulating body 1.
When pressing switchboard 4, the end that torsion spring 5 is arranged that is about to seesaw member 3 is pressed, torsion spring 5 pressurizeds, and now the state of a unlatching appears in switch; Continue push switch plate 4, will continue the state of opening; Trip switch plate 4, switch automatic disconnection under the elastic force effect of torsion spring 5, now switch automatically restores to stressed front state.
Embodiment bis-
As shown in Figure 4, the present embodiment is the improvement on embodiment mono-basis, with the difference of example one, is: the switchboard of the present embodiment have two and structure identical.
The various embodiments described above that are not limited to of the present utility model, such as: 1) flexure strip is spring; 2) torsion spring is provided with helical structure; Etc..All employings are equal to replaces the technical scheme formed, and all drops on the protection range of the utility model requirement.
