| 摘要 |
A novel voltage switching device operable under a first and a second source voltages is disclosed. The device, which is capable of converting one of the source voltages to the design voltage of an electrical appliance when the two are different, comprises a connector having voltage indicators representing the first and the second voltage switching positions, respectively; and a voltage switching plug having a groove and a pair of fuses for the different source voltages. The connector, in one of the embodiments, may have two pairs of guide slots arranged in a perpendicular relationship between the two pairs. The plug may have a pair of complementary members apt to be selectively engaged with any one pair of the slots when the plug is coupled with the connector. The plug can be accurately coupled with the connector in the first or the second source voltage position based on a simple reading of the corresponding voltage indicator through the groove provided in the cover.
