Abstract
The utility model discloses a kind of touch switch, comprise main body, main body is provided with and touches push rod and extend in first, second outer conductive pin, contact flat spring is provided with in described main body, this contact flat spring one end and described second conductive pin are connected and fixed, the other end is movable end, contact flat spring is provided with continuously an inclined plane and a step plane, the touch head of described shake-up push rod has the plane of orientation with this step plane corresponding matching, between touch head and main body, be provided with back-moving spring.In this touching switch structure, touch the inclined plane of shake-up and the contact flat spring of push rod, step plane is connected cooperation makes contact flat spring and the first conductive pin realize progressive contact, sharp impacts both avoiding, both making, contacts are indeformable, switch uses more reliable, longer service life.
Description
Technical field
The utility model relates to a kind of switch, particularly a kind of touch switch.
Background technology
Touch switch is parts conventional in household electrical appliance.Existing touch switch adopts the mechanical kinetic energy of moving seesaw-type to carry out contact energising, and the seesaw being used for conducting electricity produces vibration in the process of spring, easily departs from from the strong point when vibration, the phenomenon such as cause no power or mechanical kinetic energy is malfunctioning.And, all can with contact point produce violent collision when seesaw bounces at every turn, contact deflection is worn and torn, cause the useful life of touch switch shorter.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of touch switch, uses more reliable, longer service life.
In order to solve the problems of the technologies described above, a kind of touch switch of the present utility model, comprise main body, main body is provided with and touches push rod and extend in first, second outer conductive pin, contact flat spring is provided with in described main body, this contact flat spring one end and described second conductive pin are connected and fixed, the other end is movable end, contact flat spring is provided with continuously an inclined plane and a step plane, the touch head of described shake-up push rod has the plane of orientation with this step plane corresponding matching, between touch head and main body, be provided with back-moving spring.
As the improvement of technique scheme, the movable end of described first conductive pin and contact flat spring arranges first, second contact respectively.
As the improvement of technique scheme, the upper and lower both sides of described main body are respectively arranged with laterally curved button and vertical straight button, and described transverse direction curved button arranged outside has some ratchets.
The beneficial effects of the utility model are: in this touching switch structure, touch the inclined plane of shake-up and the contact flat spring of push rod, step plane is connected cooperation makes contact flat spring and the first conductive pin realize progressive contact, avoid both sharp impacts, make both contacts indeformable, switch uses more reliable, longer service life.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is one of structural representation of the present utility model;
Fig. 2 is structural representation two of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of touch switch of the present utility model, comprise main body 1, main body 1 is provided with and touches push rod 2 and extend in first, second outer conductive pin 3,4, contact flat spring 5 is provided with in described main body 1, this contact flat spring 5 one end and described second conductive pin 4 are connected and fixed, the other end is movable end, contact flat spring 5 is provided with continuously inclined plane 6 and a step plane 7, the touch head 8 of described shake-up push rod 2 has the plane of orientation 9 with this step plane 7 corresponding matching, between touch head 8 and main body 1, be provided with back-moving spring 10.In this touching switch structure, touch the inclined plane of shake-up and the contact flat spring of push rod, step plane be connected cooperation makes contact flat spring and the first conductive pin realize progressive contact, sharp impacts both avoiding, switch use more reliably, longer service life.When the plane of orientation of touch head slides into the step plane of contact flat spring, the deformation of contact flat spring remains unchanged always, can not excessively push because touching push rod and make contact flat spring deformation excessively affect reset.
Wherein, the movable end of described first conductive pin 3 and contact flat spring 5 is arranged respectively first, second contact 11,12, contact flat spring is contacted with the first conductive pin and conducts electricity more reliably, and be not easy to wearing and tearing.
The described upper and lower both sides of main body 1 are respectively arranged with laterally curved button 13 and vertical straight button 14, described transverse direction curved button 13 arranged outside has some ratchets 15, when switch is installed, dimensional fits is easier, solves different electric mounting size inconsistent and cause the problem got loose.
The foregoing is only preferred embodiments of the present utility model, as long as the technical scheme realizing the utility model object with basic same approach all belongs within protection range of the present utility model.
