What is the wear resistance of the luminescent film switch?

The wear resistance of luminescent film switches is generally good,mainly reflected in the following aspects:

Material characteristics

Panel material:Some luminescent film switches use materials such as polycarbonate(PC)or polyester(PET)as the panel,such as sand faced polyester(PET)which has excellent mechanical properties,rigidity,hardness,and toughness.It has excellent wear and friction resistance,high dimensional stability,and can maintain the integrity and smoothness of the surface well during frequent touch and pressing,reducing wear

Conductive layer materials:Silver paste ink,carbon paste ink,etc.are commonly used for printing conductive lines.Among them,carbon paste ink has good wear resistance and abrasion resistance after film formation and curing,and is not easily detached or failed due to friction,thus ensuring the electrical performance and service life of the luminescent film switch

Structural Design

Sealed structure:Light emitting film switches are mostly integral sealed structures,which can effectively prevent dust,particles and other foreign objects from entering the interior of the switch,avoid wear caused by friction of foreign objects,and enable the switch to work in a relatively clean environment,extending its service life

Contact design:The contacts are usually made vertically,and the screen printed contacts can form sufficient thickness.A layer of conductive carbon is also printed on the silver paste contacts to achieve high wear resistance and self-lubricating properties,thereby reducing the wear of the contacts during opening and closing,ensuring good conductivity and longer service life

Usage method

Simple operation:The action of the membrane switch is completed by the elastic membrane bouncing in the vertical direction,with a small creep amplitude,generally only 0.1~0.3mm,far from reaching the yield limit of the membrane.Therefore,under normal use,the wear degree is very small,and the number of uses can reach millions of times

Application environment restrictions

Although the luminescent film switch itself has a certain degree of wear resistance,if there are harsh conditions such as sharp objects,excessive friction,or frequent mechanical impacts in the usage environment,it may still cause wear and tear,affecting its performance and lifespan.
