Like, and most of the key position or adjacent position, and then cause the key switch failure, affecting the use of the switch.
The reason for the emergence of drums Most of the first thought that because the membrane switch is a very excellent feel of the product, the film inside the button will be installed a reed, when the temperature into the continuous rise.
Metal shrapnel will be different from the expansion of the panel material and drum problems, so the film panel was improved, do not use the spring, but found that when the temperature rises again when the film panel or
Still will drum package, and this time the temperature does not exceed the temperature of the film panel can withstand, so the exclusion of the metal reed caused the drum package reasons. There is also a saying because the device itself is sealed, So the people think that because the temperature continues to increase, the pressure inside the box will continue to rise, the internal pressure continues to increase through the box above the reserved outlet hole and the indicator hole on
