Voltage adjustable multi-type wiring board

A voltage adjustable multi-type wiring board comprises a shell body, wherein an outer panel of the shell body is provided with a power main switch, the power main switch is connected with a plug through a power line outside the shell body, at least one first jack and at least one second jack are formed in the outer panel of the shell body, 220V socket conductive terminals arranged in the shell body are positioned below the first jacks, the 220V socket conductive terminals are electrically connected with the power main switch, 140-190V socket conductive terminals arranged in the shell body are positioned below the second jacks, and the 140-190V socket conductive terminals are electrically connected with the power main switch through an electronic step-down device. The voltage adjustable multi-type wiring board has the advantages of simple structure and reliable operation; in addition, by adopting the voltage adjustable multi-type wiring board, the user can choose the corresponding jacks according to the power magnitude of electricity utilization devices, so that electronic products such as televisions, computers, neon lamps, lamp boxes and sound equipment operate at power voltage below 220V, thereby being conductive to reducing the heating intensity of the corresponding electronic products, reducing the incidence of failure, prolonging the service life, and having good energy-saving benefit.
