For the light touch switch, the maintenance is very important in the use process, of course, because many conditions change, so we must pay attention to the following maintenance methods to determine the normal use of the light touch switch.

1. When welding terminals, if the load is applied on the terminals, because different conditions may cause deformation, loosening and deterioration of electrical characteristics, please pay attention to the use in the trial.

2. It can avoid flux flowing from around PCB to waterproof switch body.

3. Water soluble flux may cause open source corrosion when welding, so please avoid trial use.

4. Poor contact may occur under low voltage conditions. When this condition is used, please confirm it separately.

5. Most of the products are designed and manufactured on the premise of DC resistance and load, so please determine separately when using other loads.

6. Printed circuit board mounting hole mode, please refer to the recommended size recorded in the touch switch diagram.

7. Welding twice should be done after the initial soldering part is restored to normal temperature. Continuous heating may cause deformation of the periphery, loosening of terminals, shedding and reduction of electrical characteristics.

8. Welding conditions should be set according to actual batch production conditions.

9. Please install the light touch switch on the specified installation surface and make the installation reach the level state. If the level state is not reached, it will lead to bad action.

10. The products with installation screw should be carried out within the prescribed screw force to avoid the possibility of thread damage.

11. If used in dusty environment, the dust will enter from the opening, resulting in contact failure or poor movement. Please take into account the design first.

12. Light touch switch with lamp is constructed directly by human operation. Please do not use it for mechanical detection function.

13. If it is used in the environment containing corrosive gases, it may cause poor contact and other phenomena. Please consider it first when designing.

14. In the course of operation and testing, if the load exceeds the prescribed load, the switch will be damaged. Please be familiar with it.

15. Correct custody methods:

A. Be sure to keep it in a place where it is wet, normal temperature, not exposed to sunlight and contains no corrosive gases. It is the limit within 6 months from the date of delivery. Please use it as soon as possible.

B. Within 7 days after receipt of the goods, if defective products are found, please contact us in time.

Above is the specific use of the switch, please pay more attention to these ways to ensure that the switch can be used lightly.
