Abstract

The utility model relates to a mechanical structure of microswitch, which is designed for improving the prior switch. The microswitch comprises a shell and a button extending outside the shell; one side of the button is provided with a heave, the heave surface is lower than the upper plane of the button. The utility model has the advantages that: the heave plays a role in bearing and guiding by being added at one side or two sides of the microswitch, so that a trigger can touch the microswitch correctly and reliably, and prevent misoperation, in particular to the phenomenon of which the switch cannot be touched, and can avoid the phenomenon that the button cannot be pop-up without flexibility caused by the overexertion of the trigger on touching the microswitch, thereby the life time of the microswitch can be extended.

Description

Sensitive switch

Technical field

The utility model relates to a kind of switch, particularly relates to a kind of mechanical structure of sensitive switch.

Background technology

Sensitive switch often needs to cooperate with other elements as a kind of control element, is switched on or switched off signal or circuit.Existing sensitive switch as shown in Figure 1 and Figure 2, it comprises shake-up member, the housing in the housing and stretches out the button of case lid, the other no supporter of button, when therefore button cooperates with other touch part, dislocation easily, overexertion and button is followed the string can not reset and causes malfunctioning switch, can not reach the purpose of control.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the above-mentioned shortcoming of prior art and sensitive switch that a kind of easier shake-up is provided.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

A kind of sensitive switch comprises housing and stretches out the outer button of housing that principal character is: in button one side projection is arranged, described raised face (RF) is lower than the last plane of button.

Also a projection can also be arranged at the opposite side of button.Described two projections can be equally high, also can be one high and one low.

Described projection can be triangle, trapezoidal, square and other analogous shapes.Also can be platform.

Compared with prior art, advantage of the present utility model is by increasing the projection of sensitive switch one side or two sides, play supporting and guide effect, make touch part more can correctly, reliably touch sensitive switch, avoid malfunction, particularly can not the touch switch phenomenon generation, the generation that overexertion causes button to follow the string, can not eject phenomenon in the time of can also preventing because of touch part shake-up sensitive switch, thereby the life-span of prolongation sensitive switch.

Description of drawings

Fig. 1 is the front view of existing sensitive switch;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the front view of the utility model embodiment;

Fig. 4 is the vertical view of Fig. 3;

Fig. 5 is the utility model behaviour in service figure.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 2, shown in Figure 3, the housing 2 of sensitive switch 1 has covered knob 3, and button is other two raised platform 4, and raised platform 4 tops are lower than the button top.

As shown in Figure 4, when touch part 5 touches sensitive switches, can under the guiding of raised platform 4, touch sensitive switch, can not bump askew or do not bump switch.

Because the difference of use occasion as required, also can be provided with guiding groove on projection or raised platform, be more convenient for guiding the direction of action of touch part, make touch part smooth, correct mobile, touch sensitive switch.

Claims

1, a kind of sensitive switch comprises housing and stretches out the outer button of housing that it is characterized in that: in button one side a projection is arranged, described raised face (RF) is lower than the last plane of button.

2. sensitive switch as claimed in claim 1 is characterized in that, at the opposite side of button a projection is arranged also.

3, sensitive switch as claimed in claim 1 or 2 is characterized in that: described projection can be triangle, trapezoidal or square.

4, sensitive switch as claimed in claim 3 is characterized in that: described two projections are equally high or one high and one low.

5, sensitive switch as claimed in claim 1 is characterized in that: on the described raised face (RF) guiding groove is arranged.
