Abstract
The utility model provides a little stroke seesaw button switch, includes the base, is equipped with the stationary contact mount pad in the base, is equipped with two stationary contacts on the stationary contact mount pad, being equipped with the backing sheet, the middle part that are located in the middle of two stationary contacts in the base and supporting the wane on the backing sheet, the both ends of wane are equipped with the movable contact that corresponds with two stationary contacts respectively, be equipped with transition in the base of wane top, should the transition including the free bearing, this free bearing have and supported the firmly push rod of wane, the top of transition piece is equipped with the button of being connected with the connecting portion of the piece that passes through, the wane has lower concave part, and during the push rod stretched into down the concave part, the distance between the medial surface of push rod and lower concave part was 0.55mm~0.8mm, and the distance between the rotation axis of backing sheet upper end and free bearing is 18.8mm~19.5mm. The utility model discloses a rotation angle of button is less, and the stability of wane is better, and when switch motion, pressing of button is comparatively level and smooth, vibrate lessly, and product appearance's harmony has also been improved to the while.
Description
Technical field
This utility model is related to a kind of moving seesaw-type button switch.
Background technology
Moving seesaw-type button switch on the market now, during switch motion, button flip angle is 5 ° ~ 8 °, in switch motion
When, the pressing of button is not smooth, and vibration is larger.
Content of the invention
In order to overcome the above-mentioned deficiency of existing moving seesaw-type button switch, this utility model provides a kind of flip angle less
Little stroke moving seesaw-type button switch.
The technical scheme in the invention for solving the technical problem is: a kind of little stroke moving seesaw-type button switch, the bottom of including
Seat, is provided with stationary contact mounting seat, described stationary contact mounting seat is provided with two stationary contacts in described base；
It is provided with described base positioned at the middle support chip of two stationary contacts, midfoot support sticking up on described support chip
Plate, described seesaw be respectively arranged at two ends with movable contact corresponding with two stationary contacts；
It is provided with transition piece, this transition piece includes free bearing, the both sides of this free bearing stretch out in base above described seesaw
Thus forming connecting portion, the bottom surface of this free bearing extends downwardly thus forming push rod, described push rod and described seesaw offset from
And described seesaw can be promoted with the upper end of support chip as axis of rotation；
The top of described transition piece is provided with the button being connected with the connecting portion of described transition piece；
Described seesaw has lower concave part, and described push rod stretches in described lower concave part, described push rod and described lower concave part
The distance between medial surface is 0.55mm ~ 0.8mm, and the distance between described support chip upper end and rotary shaft of described free bearing are
18.8mm~19.5mm.
Further, the rotational angle of described seesaw is 3.2 ° ~ 3.7 °.
Further, snap connection between the connecting portion of described button and described transition piece.
Using method of the present utility model is identical with existing moving seesaw-type button switch, will not be described here.
The beneficial effects of the utility model are: the flip angle of button is less, and the stability of seesaw is more preferably, dynamic in switch
When making, the pressing of button is more smooth, and vibration is less, also improves the harmony of product appearance simultaneously.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in further detail.
With reference to Fig. 1, a kind of little stroke moving seesaw-type button switch, including base 1, in described base 1, it is provided with stationary contact peace
Dress seat 2, described stationary contact mounting seat 2 is provided with two stationary contacts 3.
It is provided with described base 1 positioned at the middle support chip 4 of two stationary contacts 3, midfoot support on described support chip 4
Seesaw 5, described seesaw 5 be respectively arranged at two ends with movable contact 6 corresponding with two stationary contacts.
It is provided with transition piece, this transition piece includes free bearing 7, two epitaxial lateral overgrowths of this free bearing 7 in the base of described seesaw 5 top
Stretch thus forming connecting portion 8, the bottom surface of this free bearing 7 extends downwardly thus forming push rod 9, described push rod 9 and described seesaw 5
Offset thus described seesaw 5 can be promoted with the upper end of support chip as axis of rotation.
The top of described transition piece is provided with the button 10 being connected with the connecting portion 8 of described transition piece.Described in the present embodiment
Button 10 and the connecting portion 8 of described transition piece between snap connection.
Described seesaw 5 has lower concave part, and described push rod 9 stretches in described lower concave part, described push rod 9 and described lower concave part
The distance between medial surface d be 0.55mm ~ 0.8mm, between described support chip 4 upper end and the rotary shaft of described free bearing 7 away from
It is 18.8mm ~ 19.5mm from h, thus the rotational angle of seesaw 5 is less.In the present embodiment, the rotational angle of described seesaw 5 is
3.2°~3.7°.
