The audio and video socket circuit breaker uses a bimetallic plate connected in series with the circuit. The heat generated by the current during the overload will deform the bimetal and cause the circuit breaker to trip. A remarkable advantage of a thermal protector is that it can be reset after a trip. They can also be used as power on / off switches for protected audio video sockets.

Different types of headphone sockets, the degree of damage by static electricity is not the same, the minimum 100V static voltage will cause damage to it. In recent years, with the development of electronic components becoming integrated, the corresponding electrostatic voltage is also decreasing.

Abnormal protection such as headset socket (beyond the upper limit when working voltage, current and effective power, to prevent interference caused by false positives), automatic power-off circuit safety protection; a timing switch device for intelligent charging and intermittent control timing switch of the timer switch can be set to 10 switch time, and can set the number of days per week loop;

USB mouse, USB keyboard, USB camera, USB printer, USB...... It's impossible to contact the computer does not come into contact with the USB of this popular extreme interface, but not everyone understand the USB interface, and it is ignored this into the life to verify the success of USB, we have to regard it as naturally there should be something from one side.

Since 2008, there has been constant news: headphone interfaces (headphone sockets) will be replaced by USB! However, it remains a mystery whether USB can really achieve the sound effects of 3.5mm headphone sockets.
