Voltage level: 12V switch is suitable for DC circuit, and its rated voltage is 12V. 220V switch is suitable for AC circuit, and its rated voltage is 220V (it can be different in different countries, such as 1 10V or 240V).
Carrying capacity: Due to the voltage difference, 12V switch is generally used for low-power equipment and small electronic products, and its carrying capacity is relatively low. However, 220V switch is usually used for large electrical equipment and household appliances, which needs to bear high power load.
Safety requirements: Since the voltage of 220V belongs to the high voltage range, insulation and safety of the switch are required to ensure the prevention of electric leakage, fire and other dangers. In contrast, the 12V switch works in a low voltage range, and the safety requirements are relatively low.
Usage environment: 12V switch is usually used in electronic equipment, automobile circuits, low-voltage lighting and other fields. 220V switches are mainly used in electrical systems in the fields of home, commerce and industry, such as lighting, sockets and air conditioners.
When selecting the switch, it should be considered comprehensively according to the specific needs and application scenarios. 220V switch is a more suitable choice if it needs to deal with high-power load or be used in domestic, commercial and industrial fields. However, 12V switch is more suitable for low power load and specific applications.
2V switch:
1. Advantages:
Low-voltage operation: because it works at the low voltage of 12V, it is relatively safe and reduces the risk of electric shock and fire.
Suitable for low-power equipment: 12V switch is suitable for handling low-power loads, such as electronic equipment, LED lighting, automobile circuits, etc.
Miniaturization design: Due to the requirements of low voltage and low power, the 12V switch is usually small in size, which is suitable for compact space or small equipment.
2. Disadvantages:
Limited power carrying capacity: Limited by low voltage, the 12V switch has low carrying capacity, which is not suitable for high-power equipment or high-current load.
Limited application scope: 12V switch is mainly used in specific fields, which cannot meet the needs of high-power loads or household appliances.
Adapter requirements: When using the 12V switch, it may be necessary to use an adapter to convert the high voltage into 12V voltage.
220 volt switch:
1. Advantages:
High voltage operation: 220V switch is suitable for AC circuit, can handle high voltage load, and is suitable for household, commercial and industrial fields.
High power carrying capacity: due to high voltage, 220V switch has strong carrying capacity, which can handle large electrical equipment and household appliances.
Widely used: 220V switch is widely used in lighting, sockets, air conditioners and other household appliances and commercial electrical equipment.
2. Disadvantages:
Safety risk: Due to the high voltage, the requirements for safety are higher, and additional protective measures are needed to prevent electric shock and fire.
Large volume: Due to the requirements of high voltage and high power, the 220V switch has a large volume and is not suitable for small equipment or electronic products.
The following factors should be considered comprehensively when selecting 12V switch and 220V switch:
1. voltage requirements: first, confirm the voltage requirements of the equipment or circuit to be controlled. If the voltage is 12V, select the 12V switch; If the voltage is 220 volts, select the 220 volt switch.
2. Load requirements: determine the load power to be controlled. If the load is low-power equipment or small electronic products, such as LED lighting, automobile circuits, small motors, etc. , then 12V switch is a more suitable choice. For high-power equipment or household appliances (such as air conditioners, washing machines, electric water heaters, etc. ), a 220V switch is required.
3. Application scenario: Select the appropriate switch according to the specific application scenario. The following are some common application scenarios:
The application scenario of 12V switch;
Electronic equipment: suitable for small electronic products and circuit board control.
Automobile circuit: suitable for vehicle electrical system and lighting control.
LED lighting: Suitable for low-power LED strip, LED lamps, etc.
Application scenario of 220V switch:
Household appliances: suitable for power switches of air conditioners, televisions, washing machines, refrigerators and other household appliances.
Commercial equipment: suitable for commercial lighting, elevator control, office equipment, etc.
Industrial field: suitable for the control of high-power motors and high-voltage equipment.
4. Safety considerations: Whether you choose 12V switch or 220V switch, safety is very important. Please ensure that the relevant electrical safety codes and standards are observed, and the installation and maintenance are carried out by qualified professionals to prevent safety risks such as electric shock and fire.
