1. Different functions
As a type of power supply, switching power supply is mainly used to convert input AC power into stable DC power to power electronic equipment. The main function of the power switch is to control the turning on and off of the power supply to achieve the purpose of controlling the power supply of electronic equipment.
2. Different usage methods
The use of switching power supply needs to be connected to the circuit and work by connecting the input and output terminals of the power supply and the load. The power switch is directly connected to the output terminal of the power supply and the device, and controls the power on and off by turning the power switch on or off.
3. Different functions
The main function of the switching power supply is to convert the input alternating current into stable direct current, which can ensure the stability of the output current and voltage. The power switch does not involve the conversion of current and voltage, but mainly plays the role of controlling the circuit power supply.
3. Application of switching power supply and power switch in circuits
In electronic equipment, switching power supplies are widely used, such as computers, mobile phones, etc. Power switches are widely used in power control of electronic equipment, such as audio, television, etc.
4. Summary
Although switching power supplies and power switches have similar names, their functions, usage and functions are very different. Understanding their differences is critical to the proper use and maintenance of electronic equipment, as well as circuit design.
