Introduction to the precautions of the double action switch
Double action switchIt is a common electronic component and is usually used in switching circuits. The characteristic is that it generally takes two steps to turn on or off, so it is also called a double-action diode. Although this kind of switch is more convenient in use, if you do not pay attention to some details, it may cause a short circuit or damage the components. Here are some notes:
1. Confirm the two positions of the switch
Before using the double action switch, carefully confirm the two positions. Usually this switch includes forward and reverse two positions, and the wiring may also be different. Wiring and use can only be carried out after confirming the two positions.
2. Do not switch when the circuit is in operation
Double action switches are not suitable for switching when the circuit is in operation. Because in this case, the switch may cause a current short circuit or damage to electronic components, thereby endangering safety. So before the switch operation, be sure that the circuit has stopped working.
3. Do not over-stretch or compress the switch
The shell of the double action switch is usually plastic or metal material, and the internal structure under the shell is very precise. Therefore, excessive stretching or compression may cause damage to the structure, thereby affecting the normal operation of the switch. So in the use of the process must be light, do not use too much force.
4. Avoid excessively hot or humid environments
Double action switches generally cannot be used in excessively hot or humid environments. If exposed to this environment for a long time, the structure of the switch may be oxidized, rusted or corroded, which will affect the normal operation of the switch. Therefore, this environment should be avoided during use.
5. Confirm the service life of the switch
The double action switch also has a life limit. Under normal circumstances, its service life is about 100000 times. Once this number is exceeded, the switch may be damaged, affecting the normal operation of the circuit. Therefore, during use, we must pay attention to confirm the service life of the switch and replace it in time.
6. Select the appropriate switch model
There are many models of double-action switches, and the scope and performance of each model are different. Therefore, before use must choose the appropriate model, and according to the use of the requirements of the correct wiring and installation.
