(1) Durability: the film switch can be used for a very long time, can be used a million times, the long life is due to the switch's action is very simple. Because the film switch has to be constructed relatively simple. The whole is also sealed. Feel free to cause damage easily. The main work control switch, the usage rate is not very frequent, also not easy to wear, so the use of time is very long.
(2) Good sealing performance: because the film switch is a whole sealed parts, the contacts of the switch are not disturbed by the external environment, so do not worry about corrosion, also not easy to produce oxidation;
(3) The volume is relatively small, the mass is also relatively light: the size of the film switch is generally very small, but the above also has to design a lot of keys, so this requires the design of reasonable film switch, film switch excellent characteristics to ensure that the film switch is both beautiful and practical.
