Toggle switching power supply is a kind of power supply that uses modern power electronics technology to control the time ratio of switch 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 the power supply, the interest of both grows with the increase of the output power, but the growth rates of the two are different. The cost of the linear power supply 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 development space for switching power supply.

How to choose a good toggle switch is very important to our life. The metal switch below will share how to choose toggle switch for you!

1. Look at the appearance

The appearance and surface of the toggle switch should be smooth. The plating process should also be smooth, and it should be shiny under the sun

2. Look at the feel

Most high-quality switches are made of high-quality materials such as bulletproof rubber, which have high fire resistance, moisture resistance, and impact resistance. The surface is smooth. When buying, you should consider the feel of your own touch, and use the feel to determine the material of the switch. And ask the dealer. Generally speaking, the performance of imported uv lamp supplier products whose surface is not smooth and feels thin and brittle is unreliable. The panel of a good switch socket requires no bubbles, scratches, or stains on the paint spray gun. The touch of the switch is light and not tight, the socket of the socket needs to be equipped with a protective door, and the plug should be plugged in and out with a certain amount of force and cannot be inserted into the single foot.
