Four Features Of Membrane Switch

- Nov 02, 2017 -

Membrane switch is in the flexible polycarbonate or polyester membrane made of conductive paste printing contact circuit switch, is one of the contact switch.

Membrane switch for planar, multilayer combination, sealed structure, is the collection button switches, panels function markers, reading showed transparent window, light hole and circuit for the integration of electronic engine control system of the assembly.

It has the following four characteristics:

(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, switch contact is vertical contact, wear 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 metal 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
