Types of USB sockets on the market

1. Straight through usb socket (features: no button, no indicator light or usb socket with indicator light, lower cost.)

Since the usb socket market is still in its infancy, and there is no perfect safety index for the usb socket standard, many low-cost usb sockets in the market are mostly straight-through usb sockets. It is quite similar to the standby TV, which greatly reduces the lifespan and poses a greater safety hazard.

2. USB socket with button (features: built-in button, usb socket with or without indicator light, high safety performance)

There is a USB socket with a button outside, and the USB circuit is integrated into a button. When the button is pressed, the USB is powered on, so that the USB does not have to be in contact with the household voltage all the time, and the potential safety hazard is greatly reduced.

3. Automatically turn on and off the usb socket (feature: with or without indicator light, built-in switch, that is, the switch is turned on when plugged in, and the switch is turned off when pulled out)

Because the button usb socket is not humane enough, most people will forget to turn off the button when they unplug the usb cable. Some buttons are too old-fashioned, and they are all turned on and off by pressing, so that people can't figure out whether the usb is on or off, so that the button is useless. , So there is an automatic on-off usb socket. There are currently two types of switches for automatic on-off of the usb socket: door switch and inner core switch (micro switch); suitable for public places, such as coffee shops, leisure halls, etc.... ..

The door type means that there is a door at the usb exit. When inserted, the door is concave inward, which makes the switch open and the usb runs; (but sometimes it may get stuck, so the inner core switch is a micro switch) The type switch (micro switch) means that there is a micro switch inside the USB, and the switch will be triggered when it is inserted, and the USB will run.

{Misunderstanding: The indicator light does not mean the usb socket is automatically turned on and off. The indicator light only means that there is normal power on when plugged in, and whether the plug is plugged in normally, not whether it is powered on when it is in standby. The inner core type automatic on-off usb socket belongs to the patent of very few brands, and there is usually a label on the side of the automatic on-off}
