PURPOSE:To prevent supply of voltage of transformer etc. which is higher than the allowable range by selecting the wiring through operation of switch in the input plug by using an adapter in case power source voltage is different. CONSTITUTION:A switch is provided within a plug 4 to which an input power source voltage is applied. An adapter 6 is formed in such a way as being inserted into the plug 4. In case a power source voltage is supplied from a receptacle 5' with specified voltage of 220-240V, the adapter 6 is connected to the plug 4 and the adapter 6 is connected to the receptacle 5'. The switch in the plug 4 is set so that a voltage is supplied to the 230V input terminal of the transformer 2. |
