Embodiment：
Below in conjunction with the accompanying drawings and the utility model is described in detail embodiment：
A kind of microswitch as shown in Figures 1 to 8, including housing 1 and sliding block 2, and fix peace successively from top to bottom
The first static contact 4, the second static contact 7, the 3rd static contact 8, the 4th static contact 11 on housing 1, in addition to first dynamic touch
First 5 and second moving contact 10, the contact point of the static contact 8 of the first static contact 4 and the 3rd is down-set, second static contact
7 and the 4th the contact point of static contact 11 set up, the contact point of the upper and lower faces of the first moving contact 5 corresponds respectively to
One static contact 4, the contact point of the second static contact 7 are set, and the contact point of the upper and lower faces of the second moving contact 10 is corresponded respectively to
3rd static contact 8, the contact point of the 4th static contact 11 are set, and the sliding block 2 is slidably mounted in the inside chute of housing 1, and
And the sliding block 2 can be made to offer the first spring on upper and lower relative slip, the inside center axis of sliding block 2 relative to housing 1
Groove 21 and second spring groove 22, the both sides of the sliding block 2 are symmetrically arranged with the 3rd spring groove 23 and the 4th spring groove 24, described
One spring groove 21, the 3rd spring groove 23, second spring groove 22, the 4th spring groove 24 are set gradually from top to bottom, first bullet
It is provided with spring groove 21 in first spring 3, the second spring groove 22 and is provided with second spring 9, is set in the 3rd spring groove 23
There is the 3rd spring 6, and the part of the 3rd spring 6 is exposed in the first spring groove 21, and is provided with the 4th spring groove 24
Four springs 12, and the part of the 4th spring 12 is exposed in second spring groove 22, and first moving contact 5 is arranged on the first spring
3 and the 3rd between spring 6, and second moving contact 10 is arranged between the spring 12 of second spring 9 and the 4th, and first dynamic touches
First 5 and second moving contact 10 can be moved up and down respectively in the first spring groove 21, second spring groove 22, the He of the 3rd spring 6
The stiffness factor of 4th spring 12 is respectively greater than the first spring 3 and the stiffness factor of second spring 9.
Because the stiffness factor of the 3rd spring 6 and the 4th spring 12 is respectively greater than the stiffness of the first spring 3 and second spring 9
Coefficient, as shown in figure 5, by the 3rd spring groove 23,24 two end faces of the 4th spring groove after the 3rd spring 6 and the installation of the 4th spring 12
Position is limited, therefore, the 3rd spring 6 and the 4th spring 12 can not be stretched and can only be compressed, and the first moving contact 5 is first
Stable state is in the presence of both springs 6 of spring 3 and the 3rd elastic force, the second moving contact 10 is in the bullet of second spring 9 and the 4th
Stable state is in the presence of both springs 12 elastic force, now, as shown in figure 1, the first moving contact 5 is connected with the second static contact 7,
Second moving contact 10 is connected with the 4th static contact 11.
Sliding block 2 is promoted to move upwards, because the stiffness factor of the 3rd spring 6 and the 4th spring 12 is respectively greater than the first spring
3 and the stiffness factor of second spring 9, therefore, the first moving contact 5, the second moving contact 10, the 3rd spring 6, the 4th spring 12 and
Sliding block 2 is moved upwardly together, and compresses the first spring 3 and second spring 9, until the first moving contact 5, the second moving contact 10 is tactile
Head point is contacted with the first static contact 4, the 3rd static contact point respectively, now, and total elastic force of the 3rd spring 6 is still more than the first spring
3 total elastic force, total elastic force of the 4th spring 12 is still more than total elastic force of second spring 9, so the contact point of the first moving contact 5
With the contact of the contact point of the first static contact 4, the contact point of the second moving contact 10 is contacted with the contact point of the 3rd static contact 8,
Contacted for independent pressure, and then realize the conversion of on off operating mode.
The contact point of first moving contact 5 and the above and below of the second moving contact 10 uses riveted structure, for the ease of carrying out riveting
Connect operation, the contact point in the vertical direction of the above and below of 5 and second moving contact of the first moving contact 10 staggers setting.
As shown in Figure 5 and Figure 6, in actual use, in order to avoid the 3rd spring 6 deviates from the 3rd spring groove 23, the 4th bullet
Spring 12 deviates from the 4th spring groove 24, and therefore, the upper and lower plane of the 3rd spring groove 23 and the 4th spring groove 24 is symmetrical arranged
There is the semicolumn 101,102,103,104 deviate from for limited spring.
It is emphasized that：It the above is only preferred embodiment of the present utility model, not the utility model appointed
What formal limitation, every any simple modification made according to technical spirit of the present utility model to above example, etc.
With change and modification, in the range of still falling within technical solutions of the utility model.
