Tips for lightly touching the membrane switch
Here are the precautions for using the touch switch:
What are the problems that we tend to ignore when using the touch switch? This paper will introduce in detail the matters that we need to pay attention to when using the touch switch, the specific content is as follows:
① As for the setting of welding conditions, please proceed according to the actual conditions of mass production.
(2) Please avoid using water-soluble flux because it may cause switch corrosion during welding.
③ If it is used in excess of the rated voltage, there may be bad contact. Please confirm separately when it is used in the above situations.
④ Please note that the circuit setting (software setting) should be made into combined parts according to the jumping and oscillation specified by each switch type to avoid misoperation.
(5) The carbon contact point has the characteristic that the contact resistance changes due to the push load. For electric voltage divider circuit, please use after confirmation.
⑥ The products are designed and manufactured on the premise of dc resistance load. When using other loads (inductive load (L), capacitive load (C)), please confirm separately.
⑦ Can not be cleaned. For the horizontal shaft type, press the switch part as far as possible. For hinge structure, the position of shaft and rod will move when pressed, please pay special attention.
⑧ If the use of switch machine around the material corrosive gas, will likely cause poor contact and other phenomena, so please confirm in advance.
⑨ When welding terminals, if load is applied to the terminals, loosening, deformation and deterioration of electrical properties may occur due to different conditions, please pay attention to it during use.
⑩ Do not use the device continuously for a long time near the upper or lower limit of the operating temperature range. Please note that it shall be within the scope of the various environmental tests specified in the product specifications under the conditions of use.
