The purpose of description specific embodiment, it is not intended that in limitation the utility model.
Fig. 1 to Fig. 8 is please referred to, is switched for the dual reset of one better embodiment of the utility model, including bottom case component 10,
Connect the key 30 of shell component 20 in the middle shell component 20 and pivot joint of bottom case component 10.
The bottom case component 10 includes pedestal 11, the first conductive sheet 12 for being installed on 11 middle part of pedestal, abuts the first conduction
The movable contact flat 13 of piece 12 and the second conductive sheet 14 for being installed on 12 opposite sides of the first conductive sheet；Movable contact flat 13 it is opposite
Both ends abut the second conductive sheet 14 for activity.
One end of first conductive sheet 12 is located in pedestal 11, and the other end wears and exceeds the side of pedestal 11；First is conductive
One end that piece 12 is located in pedestal 11 offers location hole 120, and location hole 120 is for the movable contact flat 13 that is located by connecting.In this reality
It applies in example, the V-shaped setting of the movable contact flat 13.Movable contact flat 13 includes abutting part 131, is connected to abutting part 131 opposite two
The free end 132 of side and the movable contact 133 being installed on free end 132.The correspondence of abutting part 131 is contained in location hole 120,
Free end 132 corresponds to the second conductive sheet 14.Specifically, in the present embodiment, one end of the second conductive sheet 14 is located in pedestal 11,
The other end wears and exceeds the side of pedestal 11；Second conductive sheet 14 is located at one end in pedestal 11 with stationary contact 140, stationary contact
The corresponding movable contact 133 of point 140.Since the first conductive sheet 12 and the second conductive sheet 14 are the sides for wearing pedestal 11, compared to
Traditional conductive sheet wears the bottom surface of pedestal, and the height of the dual reset switch in the present embodiment is opposite to become smaller, to be adapted to more
Small installation space.
In the present embodiment, the opposite sides of pedestal 11 is also protruded out respectively with multiple fixture blocks 15, used in being correspondingly connected with
Shell component 20.
The middle shell component 20 includes in the middle shell 21 of hollow setting, the platform 22 being connected in middle shell 21, connecting platform
22 backwards to 11 1 face opposite end of pedestal pillar 23 and be arranged the reset spring 24 of pillar 23.The middle part of platform 22 is equipped with and passes through
Perforation 25, through hole 25 run through the opposing sides of platform 22, and one end that through hole 25 is used to accommodate key 30 is worn.Middle shell 21 leans on
Uniform intervals are equipped with bayonet 26 on the opposite sides face of nearly 11 one end of pedestal, and bayonet 26 corresponds to fixture block 15, shell 21 and bottom in realization
Seat 11 is located by connecting, so that the first conductive sheet 12 and the second conductive sheet 14 are set between middle shell 21 and pedestal 11, guarantees to connect
The stability connect.Middle shell 21 is respectively provided with lug 27 on the opposite sides face far from 11 one end of pedestal, lug 27 exceeds middle shell 21
The end face of one end.The middle part of lug 27 offers pivoted hole 28, for being pivotally connected key 30.
The key 30 includes keycap 31, is connected to 31 opposite sides of keycap shaft 32, from the middle part of keycap 31 bottom of towards
11 directions of the seat fixed part 33 extended and the push plate 34 being installed in fixed part 33 and pressure spring 35.In the present embodiment, keycap 31
It is arranged in cover shape, keycap 31 is contained in middle shell 21, and keycap 31 is provide with reset spring 24, and the top of 31 inner wall of keycap abuts
Reset spring 24.Shaft 32 corresponds to pivoted hole 28.Fixed part 33 is in hollow setting, and one end of pressure spring 35 is connected in fixed part 33
The other end at the top of wall, pressure spring 35 abuts push plate 34.Fixed part 33 wears through hole 25, and push plate 34 is for abutting movable contact flat
13。
As shown in fig. 7, keycap 31 is rotated along shaft 32 in use, applying external force in any end of keycap 31,
One end of keycap 31 sinks and pressed home spring 24, at this point, fixed part 33 deflects, push plate 34 is under the promotion of pressure spring 35
It is connected to a free end 132 of movable contact flat 13, free end 132 sinks, and movable contact flat 13 deflects, so that movable contact 133 supports
Stationary contact 140 is connect, abutting part 131 abuts the first conductive sheet 12, realizes the electricity between the first conductive sheet 12 and the second conductive sheet 14
Connection.After removing external force, reset spring 24 resets, and key 30 is driven to reset, and push plate at this time 34 is connected in movable contact flat 13
Portion, movable contact flat 13 reset, and movable contact 133 is far from stationary contact 140.Wherein, lug 27 exceed middle shell 21 so that lug 27 with push away
The distance between plate 34 increases, to increase the radius of turn of key 30, when push plate 34 rotate similarly apart from when, keycap 31 needs
The deflection angle wanted is smaller, it appears and it is more laborsaving convenient, to the more adaptable of small installation space.
Above-mentioned dual reset switch, structure is simple, easy to use, and middle 21 one end of shell is equipped with lug 27, and lug 27 exceeds middle shell
The end face of one end, key 30 are pivotally connected lug 27, and the both ends of key 30 carry out pressing by a small margin respectively, fixed part 33 can be driven
And the push plate 34 being installed on inside fixed part 33 deflects, push plate 34 pushes movable contact flat 13 to deflect, so that movable contact flat 13
The first conductive sheet 12 and the second conductive sheet 14 are connected, realizes conducting, it appears it is more laborsaving, it is also opposite to improve service life.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
