1. Automatic power-off. Compared with traditional TR standard sockets, the feature of TR standard sockets with protective doors is reflected in its intelligence: when children play with the socket, the socket will automatically power off, mainly using infrared sensing technology. Only when children leave the infrared sensing range, the socket will be powered on, and the power will not be cut off when there is a load on the socket. Only when children play with the socket will the power be cut off, effectively protecting childrens electrical safety.

2. Safety protection door. On the basis of automatic power-off function, a safety protection door has been added. Generally, traditional American standard sockets do not have them.

3. Voice controlled alarm. This is also a function that traditional American standard sockets do not have, when there is a safety error in the socket, such as the reverse connection of the fire and neutral wires. At this time, the socket will emit an alarm sound to remind of safety errors. To avoid safety hazards caused by incorrect installation of sockets that fail to achieve protective effects.
