In on same vertical line.
As a kind of preferable technical scheme of the utility model, the thickness of the film face-plate is 0.15-0.25mm, described
The thickness of mucigel is 0.05-0.15mm.
As a kind of preferable technical scheme of the utility model, the upper contact is shaped as downward concavity, under described
Shell fragment is shaped as upward convex.
As a kind of preferable technical scheme of the utility model, the line layer side is additionally provided with lead-out wire.
As a kind of preferable technical scheme of the utility model, the quantity of the compression spring is two, and is located at respectively
Between inner contact and two outer contacts.
Compared with prior art, the beneficial effects of the utility model are：The utility model is by pushing in briquetting
Contact is contacted with lower shell fragment, and lower shell fragment moves downward to be contacted with inner contact so that outer contact connects with inner contact, by
Lower shell fragment bottom is provided with compression spring, because lower shell fragment is often in excessively anti-recessed state, adds lower shell fragment and recovers former
The performance of shape, avoid long-term use can be so that the phenomenon not rebounded occurs in lower shell fragment, global design is novel, simple in construction, button
Good hand touch, the clear and melodious sound can be heard during operation, allow an operator to know operational circumstances, avoid repeating, and pressure is set
Spring adds the durability of thin film switch, avoids the occurrence of not rebound phenomenon.
