Toggle switching power supply is a kind of power supply that uses modern power electronics technology to control the ratio of time when the switch is turned on and off, and maintains a stable output voltage. The switching power supply is generally composed of pulse width modulation (PWM control IC and MOSFET). Switching power supply and linearity. Compared with the power supply, the interest rate of both increases with the increase of output power, but the growth rate of the two is different. The linear power supply cost is higher than the switching power supply at a certain output power point, which is called cost reversal. With the development and innovation of power electronics technology, switching power supply technology is also innovating from time to time. This interest reversal point is increasingly moving to the low output power end, which provides a broad space for development of switching power supplies.

How to choose a good toggle switch has a very important effect on our life. Next, let's talk about what aspects you should pay attention to before purchasing the toggle switch:

Look at the appearance

Toggle switch switch appearance, surface should look smooth. The plating treatment should also be smooth, and it should be bright in the sunlight.

2. Look at the feel

Most of the good quality switches are made of high-grade materials such as bulletproof rubber. The fireproof performance, moisture resistance and impact resistance are high, and the surface is smooth. When purchasing, you should consider the feel of your own touch, and determine the material of the switch by hand. And ask the dealer. In general, the imported UV lamp supplier products whose surface is not too smooth and feels thin and brittle, the performance is unreliable. A good switch socket panel requires the paint spray gun to be free of air bubbles, scratches, and smudging. The touch of the switch is light and not tight, and the socket of the socket needs to be equipped with a protective door. The plug should be inserted and removed with a certain force and the single foot cannot be inserted before selecting the toggle switch.
