The Lifetime Of The Film Key Is Reliable

- Apr 06, 2017 -

Film key technical conditions of life expectancy should be greater than 1 million times, in the actual application of the operation, the circuit layer film under the operating pressure change, 0.1--0.3mm switch itinerary decided it is very small deformation, far from the film's fatigue limit.

If not strictly adhere to the design of the film key, the process specifications, resulting in the thickness of the insulation layer unreasonable, the air flow in the groove is unreasonable, will lead to the circuit layer film deformation intensified, resulting in reduced film key life. In addition, the life of the film key depends on the circuit contact wear. The silver paste can be printed on a layer of carbon paste, improve wear resistance, prolong the life of the switch.
