It has the following features:
(1) the durability
Membrane switch life generally can reach more than one million times, it has been such a long life, is because of the switch action only by elastic film vertical bounce.Elastic film, though after one million times of peristalsis, but as a result of creep was small, only 0.1 ~ 0.3 mm (both switch trip), and the rationality of the selection of materials, far from reach the yield limit of film, so the life of the membrane material to withstand more than one million times without deformation.On the other hand, the contact of the switch
Contact is vertical, the wear quantity is very small;And silk screen printing can contact form enough thickness, and the printing on the silver pulp contact a layer of conductive carbon, in order to achieve high wear resistance, self-lubrication purposes, therefore the service life of membrane switch, dozens of times higher than that of mechanical contact switch.
(2) the sealing performance is good
Due to the membrane switch is whole sealing structure, switch contact is not affected by the erosion of harmful gases, not easy oxidation;Has the characteristics of waterproof and dustproof, making it suitable for all kinds of bad environment.
(3) small volume, light quality and reliable structure
Membrane switch keyboard in the design of permutation and combination into film, its setting density is big, and it is made up by multilayer film sealed chip type structure, all cables between switches and lead by screen printing is one-time completed, the total thickness in 1 ~ 3 mm, narrow the volume, therefore, reduce the quality, improve the reliability.
(4) the rich color and beautiful shape
Membrane switch can according to user's design concept, on the design of the colour of the design embodies individuation, in adornment effect reflect the material beauty, decorative beauty, technology beauty comprehensive characteristics.
(5) reduce 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.For the installation of paste type and membrane switch, as long as read back tape, can tightly paste on the surface of the whole machine, its export wire inserting machine rear circuit socket, instantaneous can connect circuits.Province, material, reduces the cost of form a complete set of the machine.
