In the process of selecting light touch switch, the life of switch is usually determined by metal shrapnel material. At present, the shrapnel materials of conventional switches are divided into two kinds: phosphorus bronze shrapnel and rust steel shrapnel. Generally speaking, the relative cost of stainless steel shrapnel is generally very high, but for the shrapnel with relatively long service life, the macro-electronic suggestion of touch switch manufacturer suggests that you can choose the material of this shrapnel. So, what are the reasons for the easy damage of the light touch switch?
Because the base of touch switch is not completely sealed, it does not have 100% waterproof performance. Therefore, pay attention to the normal use of switches, do not have water vapor, oil and other liquids. Prevent the flow of water from the button space into the switch, so that once the line is exposed to humid environment, it will cause dangerous leakage risk.
For the use of light touch switch, do not impose excessive vibration or impact on the key force of operation. Contact may cause faults, jamming, damage, etc. In addition, it is used under the condition of continuous vibration and impact. With the generation of wear residue, it will cause contact failure, failure and other problems, shorten the service life.
Operate in the temperature and humidity range specified by the touch switch, because most switch buttons are caused by resistance of some silicon material. If the temperature is high, the touch of the button may decrease. In addition, if the temperature changes dramatically, the silicone resin of the switch may be deformed or damaged. Therefore, when installing switches, it is necessary to avoid using switches in some high temperature environments.
Secondly, for a long time without touching the switch, because the internal shrapnel of the switch is composed of some metal parts, it will lead to air humidity, so it will also affect the quality of the switch performance. The reactions of shrapnel elements with oxidation and other reactions can easily lead to oxidation of some components in subsequent settings. Then, on the back, the touch sensitivity of some buttons decreases, which will affect the reduction of the switch.
