The square light touch switch often has some problems when it is used, and we can avoid it effectively when we use it. What is the problem? Let's give you a detailed introduction.
Problems needing attention in the use of square touch switches
1, when the square light touch switch terminal is welded, if the load is applied on the terminal, it will be loose because of the different conditions, the deformation and the deterioration of electrical characteristics may be deteriorated. Please pay attention to the use when using.
2. When the effect of the thermal stress is changed when using the through - hole printed circuit board and the recommended circuit board, the welding condition is confirmed in advance.
3. When carrying out the two welding, please return to the normal temperature after the first welding part. Continuous heating may cause deformation of the outer part, loosening of the terminals, shedding and electrical characteristics.
4. Regarding the setting of welding conditions, it is necessary to confirm the actual batch production conditions.
5, the product is designed and manufactured based on DC resistance load. When using other loads [inductive load, capacitive load], please confirm separately.
6. Printed circuit board mounting holes and models, please refer to the recommended size in the product drawings.
7. Introduce the switch to be operated directly by the operator according to the switch. Please do not use the mechanical testing function.
8. When the square touch switch is operated, if the above load is applied, the switch will be damaged. Please be careful not to apply the above force on the switch.
9. Please avoid the use of the operating department from the side.
10. For the shaft type, press the center of the switch as far as possible. For hinge structure, press the shaft lever position to move when pressing. Please pay special attention to it.
11, switch installation, because of other parts such as hardening of the binder through heat storage hardening furnace, please contact with professionals.
12, if the surrounding material of the switch is used to produce corrosive gases, it will be possible to cause bad contact and so on, so please make full confirmation in advance.
13. The carbon contact point is characterized by the change of contact resistance due to push load. For voltage divider circuit, etc., please use it after full confirmation.
14. Introduction of models other than closed type, please pay attention to the invasion of foreign objects.
The above is the problem that should be noticed when using the square touch switch.
