12 between the first cavity volume and the second cavity volume, and the middle part of guiding conical plate 12 is equipped with the through hole passed through for movable contact 32, and through hole connects
Logical first cavity volume and the second cavity volume.
As shown in Fig. 2, when pushing pressing section 33 to the left by right side, spring is compressed, pressing section 33 drive quarrel portion 30b to
Case inside move, quarrel portion 30b extruding breath oral area 300 enter guiding conical plate 12 and keep bottom plate 20 between, chassis portion 30a to
The outer circumferential side movement of second cavity volume, chassis portion 30a are extruded and drive fold ring 301 to deform, and breath oral area 300 is also moved to periphery
Dynamic, the accommodating chamber 302 at middle part is opened, and the contact bar portion 320 of movable contact 32 passes through the through hole of guiding conical plate 12 and first
Contact site 100 contacts, and realizes second connecting portion 110, the electric connection of 32 and first contact site 100 of movable contact, at switch module
In connected state.
As shown in Figure 1, when 33 no longer stress of pressing section, under the reset response of spring restoring force, to outside housing
Side ejects pressing section 33, and quarrel portion 30b pulls to the right reset, and chassis portion 30a is replied from the both ends of the second cavity volume to middle part, living
Moving contact 32 follows quarrel portion 30b to be moved from enclosure interior to outside, and breath oral area 300 also has outside to enter the sleeve for keeping set 2
In 21, due to sleeve 21 barrel internal diameter be less than breath oral area 300 thickness, breath oral area 300 under the action of spring pulls power in
The junction of sleeve 21 and holding bottom plate 20 mutually extrudes, and accommodating chamber 302 is closed, disconnects 302 and first cavity volume of accommodating chamber
Connection, keeps covering 2 leakproofness for adding breath oral area 300 by rigid.
Pressing section 33 is used as using the plastic material of hard and presses button, and is coordinated spacing barrel 13 and pressed tegmental wall 330, can
So that pressing section 33 has certain anti-bending strength, even if Impact direction generation is crooked during pressing, will not to press
Portion 33 can not stretch.
Movable contact 32 is in T-shape, includes the contact bar portion 320 of contact end 321 and conduction, is opened up in quarrel portion 30b
There are bar portion lock chamber 310 and end lock chamber 311, end lock chamber 311 is located at the one of the corresponding silica gel leather cup 30 of pressing section 33
Side, contact bar portion 320 are fixed in bar portion lock chamber 310, and contact end 321 is fixed in end lock chamber 311.
Bar portion lock chamber 310 and end lock chamber 311 effectively improve movable contact 32 in the fixation in silica gel leather cup 30, prevent
Only its offset produced in the deformation of rubber cup 30 and moving process and dislocation abjection phenomenon.
First contact site 100 of the first wire connection terminal 10 uses memory alloy material, and the first contact site 100 includes end
1000th, the arc contact portion 1001 and heating contacted for same movable contact makes arc contact portion 1001 separated with movable contact 32 curved
Folding part 1002；End 1000 is located at the both ends of the first contact site 100 and is fixed with enclosure interior, and bending part 1002 is touched positioned at arc
Between portion 1001 and end 1000.
The memory alloy material used in the present embodiment has a feature, i.e., curved when 100 temperature of the first contact site rises
The bending angle of folding part 1002 can become larger, and end 1000 is the fixation for 100 both ends of the first contact site.
As shown in Figure 7 and Figure 8, when the power for switching vigour part is excessive or overloads, the 100 interior electricity passed through of the first contact site
Flow larger, the heat of generation becomes more, the rising of 100 bulk temperature of the first contact site, due to 1000 both ends of end be it is fixed,
Bending part 1002 is shunk and close to both ends, and arc contact portion 1001 is overall to be deviated to the left side, and spacing is produced simultaneously with movable contact 32
Disconnected with movable contact 32, switch is off at this time, avoids electrical appliance from overloading, and ensures security.
The above makes the preferred embodiment of the present invention, does not depart from this hair for those of ordinary skill in the art
On the premise of bright principle, some variations and modifications can also be made, these also should be regarded as protection scope of the present invention.
