This may be the first time a Chinese company has made socket products for the elderly, visually impaired and behaviorally handicapped people. After conducting extensive research, Bull found that this group experiences difficulty finding the jack when using the socket. This is both inconvenient and dangerous. Therefore, they designed a self-rebounding convex cover and enlarged the jack on the convex cover with braille to help users quickly locate its position and avoid electric shock. In addition, they added a separate passive wireless switch that allows users to control the outlet without bending over.
