(1) the sealing performance is good
Due to the membrane switch is a whole sealing structure, switch contact from the erosion of harmful gases, not easy oxidation, has the characteristics of waterproof and dustproof, making it suitable for all kinds of bad environment.
(2) 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.
(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, so the volume reduced quality, improve the reliability.
(4) 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, and the installation of the membrane switch is paste type, as long as read back tape, can tightly paste on the surface of the whole machine, its export wire inserting machine rear circuit socket, moment can be connected to circuit, the province, save material, reduce the cost of form a complete set of the machine.
(5) the durability
Membrane switch life generally can reach more than one million times, it has been such a long life, as a result of switch action only by elastic thin film of 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, switch contact is vertical contact, wear is very small, and the 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.
Application: membrane switch is a kind of since its switch, applicable to the switch power is less than 1 w, maximum working voltage: 42 v (DC) or 25 v (DC), maximum working current is less than 100 ma workplace, can be widely used in all computer, numerical control, intelligent instruments, meters, instrument and same time criterion, and memory function of electronic circuit in many fields.
