When using the toggle switch in Dongguan, we should pay attention to some matters needing attention, so that it can be used safely and correctly.
In our life, such as audio equipment, electric toys and other electrical appliances in most of the electrical appliances will use Dongguan switch, the function of Dongguan switch switch is mainly through the switch handle to apply different direction of the force to achieve circuit connection and break, the use of simple so the application is very wide. Then through the continuous development of science, now this kind of switch commonly used variety is mainly two, third, four, reset and other functional switches, can be selected according to the needs of the switch. In addition, no matter what kind of gear has the features of flexible slider and stable and reliable performance, it is applied to electronic products such as digital products, instrument equipment, fax machines, medical equipment, electric toys and so on.
Attention should be paid to the following items when using toggle switches in Dongguan:
1. load the terminals when welding terminals, depending on the conditions will cause loosening, deformation and reduction of electrical characteristics.
2. because water soluble flux may cause corrosion of the switch during welding, please avoid using it.
3. for welding conditions set, please according to the actual conditions of mass production.
4. solder two times, please return to normal temperature after the first welding part. Continuous heating can cause deformation of the outer part, loosening of the terminals, shedding and reduction of electrical characteristics.
5. please do not allow the flux to flow from the top of the printed circuit board to the switch.
6. after installing the switch, in order to harden the adhesive of other parts, please contact us through the regenerative hardening furnace.
7. 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 fully confirmed in advance.
8. with a foot type, please weld in the position of the foot. If the soldering pin is fixed in a fixed position, there is possibility of deformation in the pin mechanism part.
9. can't be cleaned. When the terminal is welded, load is applied to terminals, depending on the conditions, which may cause loosening, deformation and reduction of electrical characteristics.
