Abstract
The utility model discloses a micro switch, which comprises a shell (1), a switch button (2), a movable contact piece (4) and a static contact piece (5). The shell (1) is internally provided with a limiting shaft (102). A return spring (3) is sleeved onto the limiting shaft (102). The upper part of the switch button (2) is sleeved onto the shell (1) to be in clearance fit with the shell (1). The bottom of the switch button (2) is provided with a blind hole (203). The blind hole (203) is sleeved on the limiting shaft (102). The movable contact piece (4) is provided with a bending part (401). The bending part (401) is in contact operation with an inclined plane (202) arranged on the switch button (2). The micro switch has the advantages of simple structure, small size, lower in working noise during usage and the like.
Description
Technical field
The utility model belongs to switch, is specifically related to a kind of sensitive switch.
Background technology
Sensitive switch is to have small contact separation and fast actuation mechanism, and the contact mechanism that carries out switch motion by stroke and the power of regulation, because of the less therefore named sensitive switch of its switch contact spacing, is again sensitive switch.Sensitive switch is widely used in the electric equipments such as computer mouse, vehicle electronics, communication apparatus, tester, small household appliances.Existing sensitive switch includes leverage and the resetting device of relative complex, thereby has limited the volume of sensitive switch, easily produces larger noise in the process of using simultaneously.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to provide a kind of simple in structure, and volume is small and exquisite and in use have a sensitive switch of less operating noise.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of sensitive switch, comprises shell, shift knob, movable contact spring and static contact; The inside of described shell is provided with limit shaft, on described limit shaft, is arranged with back-moving spring; The top of described shift knob is set on shell and realizes matched in clearance, and the bottom of described shift knob is provided with a blind hole, and described blind hole is set on limit shaft; On described movable contact spring, be provided with kink, described kink contacts cooperation with the inclined-plane arranging on shift knob.
Wherein, the step place of described shift knob is provided with beam.
Wherein, on described shell, offer two installing holes.
Wherein, described movable contact spring and static contact have larger surface area.
Wherein, described back-moving spring can be changed according to the large freedom in minor affairs of required pressure.
(3) beneficial effect
Compared with prior art, the utlity model has simple in structurely, volume is small and exquisite, the feature such as the operating noise that produces during use is less.
Accompanying drawing explanation
Structural representation when Fig. 1 is a kind of sensitive switch open mode of the utility model.
Fig. 2 is the structural representation after a kind of sensitive switch closure of the utility model.
Fig. 3 is the stereogram of a kind of sensitive switch of the utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The structure of a kind of sensitive switch of the utility model as Figure 1-3, comprises shell 1, shift knob 2, movable contact spring 4 and static contact 5; The inside of described shell 1 is provided with limit shaft 102, on described limit shaft 102, is arranged with back-moving spring 3; The top of described shift knob 2 is set on shell 1 and realizes matched in clearance, and the bottom of described shift knob 2 is provided with a blind hole 203, and described blind hole 203 is set on limit shaft 102; On described movable contact spring 4, be provided with kink 401, described kink 401 contacts cooperation with the inclined-plane 202 arranging on shift knob 2.
As optimization, the step place of described shift knob 2 is provided with beam 7, the impulsive force to shell 1 when described beam 7 can alleviate shift knob 2 resilience, thus reduce operating noise.
As optimization, on described shell 1, offer two installing holes 101, this installing hole plays the fixedly effect of sensitive switch while being used for assembling sensitive switch.
As optimization, adopt long wider movable contact spring 4 and static contact 5, make it have larger surface area, can in the long course of work of sensitive switch, play good heat dispersion.
As optimization, described back-moving spring 3 can be changed according to the large freedom in minor affairs of required pressure, and for different application scenarios, the pressure triggering for sensitive switch has this different requirement; Therefore can be according to the different requirements of different occasions, the spring of choose reasonable different hardness is to reach the triggering pressure needing.
During use, shift knob 2 moves downward under pressure, and under the effect of shell 1 and limit shaft 102, shift knob 2 can only move on vertically; Shift knob 2 is in the process moving downward, and the kink 401 on 202 pairs, the inclined-plane movable contact spring 4 on shift knob 2 is exerted pressure, and movable contact spring 4 is bent, and finally makes movable contact spring 4 contact with the contact 6 on static contact 5, realizes circuit communication.
After the power on shift knob 2 of being applied to is withdrawn, shift knob 2 moves upward under the effect of back-moving spring 3, the active force of the kink on 2 pairs of movable contact springs 4 of Simultaneous Switching button reduces, and movable contact spring 4 restores to the original state under the effect of self elastic force, thereby the separated loop of realizing, contact 6 disconnects.
These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
Claims (5)
