Problems solved by technology

[0002] The switch circuit of the existing light is generally to directly connect the ordinary switch in series with the light circuit. In this way, when the light switch leaks or the switch is damaged, and the internal components are exposed, the risk of over-electricity is easy to occur, and such a switch is not safe.
