The switching power supply is a kind of power supply which uses modern power electronics technology to control the time ratio of switching on and off to maintain stable output voltage. The switching power supply is generally composed of pulse width modulation (PWM control IC and MOSFET). Compared with linear power supply and switching power supply, the interest of both increases with the increase of output power, but the growth rate of the two is different. The cost of linear power supply is higher than that of switching power supply at a certain output power point, which is called cost reversal point. With the development and innovation of power electronics technology, the switching power supply technology is also innovating from time to time. This interest reversal point is moving to the low output power terminal day by day, which provides a broad space for the development of switching power supply.
How to choose a good toggle switch is very important to our life. Next, let's talk about what we should pay attention to before purchasing toggle switch.
1. look at the appearance
The appearance and surface of the toggle switch should be smooth.  Electroplating should also be smooth and bright under the sun.
2. look at the feeling of hand
High quality switches are mostly made of high-grade materials such as bullet-proof adhesive. They have high fireproof performance, moisture-proof performance, anti-collision performance and so on. The surface is smooth. When choosing and purchasing switches, one should consider the feeling one feels. The material of switches should be judged preliminarily by the feeling of hand and the dealer should be inquired. Generally speaking, the performance of imported UV lamp suppliers whose surfaces are not smooth and feel thin and crisp is not reliable. A good switch panel requires a paint spray gun without bubbles, no scratches, no stains. The handle of the switch is light and not tight. The socket socket should be equipped with a protective door. The plug should be plugged in and out with a certain force and the single foot can not be inserted into the switch before selecting the switch.
