Abstract
The invention discloses a membrane switch good in touch. The membrane switch comprises a panel layer, circuit layers and metal elastic pieces, wherein a face adhesive layer, the circuit layers and a bottom layer are arranged at the lower end of the panel layer in sequence, and the metal elastic pieces are arranged between the circuit layers. The membrane switch good in touch has the advantages that single-face wiredrawing texture processing is carried out on the surface of the panel layer, and the attractiveness and the touch of the panel layer are improved; epoxy AB adhesive is used in the face adhesive layer, and waterproof performance and high temperature resisting performance are good; the metal elastic pieces are arranged between the upper circuit layer and the lower circuit layer, adopted beryllium bronze is good in elasticity and good in dimension stability, insulation materials are arranged at corners at the upper ends and the lower ends of the metal elastic pieces, and line shorts can be prevented.
Description
Technical field
The present invention relates to a kind of thin film switch, relate in particular to a kind of thin film switch of sense of touch excellence.
Background technology
Thin film switch is an operating system that integrates keypress function, indicator elment, instrument panel, is widely used in the instrument of telecommunications, electronic measurements, Industry Control, Medical Devices, auto industry, intelligent toy, the fields such as household electrical appliance.The thin film switch of producing is in the market various informative: although plane is without sense of touch type long service life, there is no sense of touch; Although film convex surface sense of touch type has good sense of touch, useful life is short; Although chimb frame is specious without sense of touch type, third dimension is strong, without sense of touch type etc.Therefore, the invention provides a kind of new technical scheme addresses the above problem.
Summary of the invention
The invention provides a kind of thin film switch of sense of touch excellence.
The technical solution used in the present invention: a kind of thin film switch of sense of touch excellence comprises panel layer, circuit layer and metal clips, panel layer lower end is provided with face glue-line, circuit layer and bottom successively, is provided with metal clips in the middle of circuit layer.
Foregoing circuit layer comprises the doubling layer between circuit layer and lower circuit layer and upper circuit layer and lower circuit layer, and the upper end of metal clips is connected with upper circuit layer contact, and the lower end of metal clips is connected with lower circuit layer contact.
The material of metal clips is beryllium-bronze, and metal clips is Z-shaped structure, and the edge of metal clips upper and lower end is provided with dielectric film.
The material of above-mentioned panel layer is PET, and lifting by one side silk texture processing is carried out in the surface of panel layer.
The material of above-mentioned glue-line is epoxy AB glue.
Beneficial effect of the present invention: lifting by one side silk texture processing is carried out in the surface of opposite flaggy, the attractive in appearance and sense of touch of increase panel layer; Face glue-line uses epoxy AB glue, and water resistant, high temperature resistant performance is good; Metal clips is located between circuit layer and lower circuit layer, and the beryllium-bronze elastic force of employing is good, and good stability of the dimension is provided with dielectric film at the edge of the upper and lower end of metal clips, can prevent line short.

Wherein, 1, panel layer, 2, face glue-line, 3, upper circuit layer, 4, lower circuit layer, 5, bottom, 6, doubling layer, 7, metal clips, 8, dielectric film.
Embodiment
As shown in Figure 1, a kind of thin film switch of sense of touch excellence comprises panel layer 1, circuit layer and metal clips 7, and described panel layer 1 lower end is provided with face glue-line 2, circuit layer and bottom 5 successively, is provided with metal clips 7 in the middle of described circuit layer.
Foregoing circuit layer comprises the doubling layer 6 between circuit layer 3 and lower circuit layer 4 and upper circuit layer 3 and lower circuit layer 4, and the upper end of described metal clips 7 is connected with upper circuit layer 3 contacts, and the lower end of described metal clips 7 is connected with lower circuit layer 4 contacts.
The material of metal clips 7 is beryllium-bronze, and metal clips 7 is Z-shaped structure, and the edge of described metal clips 7 upper and lower ends is provided with dielectric film 8.
The material of above-mentioned panel layer 1 is PET, and lifting by one side silk texture processing is carried out in the surface of panel layer 7.
The material of above-mentioned glue-line 2 is epoxy AB glue.
Use principle: press thin film switch, metal clips 7 can produce distortion, makes circuit layer 3 and lower circuit layer 4 joints produce conduction; After hand leaves, metal clips 7 restores to the original state rapidly, and upper circuit layer 3 separates with lower circuit layer 4, and circuit disconnects.
Beneficial effect: lifting by one side silk texture processing is carried out in the surface of opposite flaggy 1, the attractive in appearance and sense of touch of increase panel layer; Face glue-line 2 uses epoxy AB glue, and water resistant, high temperature resistant performance is good; Metal clips 7 is located between circuit layer 3 and lower circuit layer 4, and the beryllium-bronze elastic force of employing is good, and good stability of the dimension is provided with dielectric film 8 at the edge of the upper and lower end of metal clips 7, can prevent line short.
