Membrane switch for planar,Multilayer composite,Sealed structure,Is the collectionKey switch,panelFunctional markers,Reading showed transparent window,Lamp hole and circuit for the integration of electronic engine control system of the assembly.
It has the followingfourFeatures:
(1Durability, long service life
The life of the membrane switch generally can reach more than one million times,Is such a long life,Is because of the switch action only by elastic film vertical bounce.Although elastic film after one million times of peristalsis,But as a result of creep was small,Only for0.1~0.3mm（namelySwitch trip),Combined with the rationality of material selection,Far not reached the yield limit of thin film,So the life of the thin film material to withstand more than one million times without deformation.On the other hand,Contact of the switch contact is vertical,Wear is very small;And silk screen printing can contact form enough thickness,And on the silver pulp contact in printing a layer of conductive carbon,In order to achieve high wear-resisting,The purpose of self lubricating,So the service life of membrane switch,Dozens of times higher than that of mechanical contact switch.
(2), sealed performance is good
Use of unique technology, can make the membrane switch has the waterproof, prevent oil, anti-pollution, anti-static interference, and other functions;Due to theMetal membrane switchThe whole sealing structure,Switch contact from the erosion of harmful gases,Not easy oxidation;Because of aThe characteristics of waterproof and dustproof,Making it suitable for all kinds of bad environment.
(3) small volume,Light and structure and reliable quality
Membrane switch keyboard in the design of permutation and combination into film,It is set density,And it is made up by multilayer film sealing sheet structure,All cables between switches and lead is performed by screen printing at once,The total thickness1~3mm,Narrowing down the volume,Reduce the quality,To improve the reliability，Very easy to carry and dismantl
(4) color is rich and beautiful appearance and easy
Membrane switch can according to user's design concept,On the design of the colour of design personalized,Teaching material beauty in adornment effect,Decorative beauty,Process comprehensive characteristics of beauty。Modern printing technology, perfect design on collocation, can make any pattern that you need
（5）Decrease the cost of form a complete set of mechanical and electronic products
The traditional mechanical switch, need to welding when installation, even with fixed bracket;whileMembrane switchFor the installation of paste type, peel off as long as the back tape, can tightly paste on the surface of the whole machine, its export lead to insert on the socket of the machine rear circuit, instantaneous can connect circuits.
