Abstract:
1. A conversion plug structure having a variable resistor, comprising: a conversion adaptor having a plurality of first terminals disposed therein; and an intermediate adaptor having: an insulating housing having a plurality of second terminals disposed therein; a variable resistor extending through an opening in said housing and being electrically connected between one of the second terminals and the power cord, the rest of the second terminals being electrically connected with the power cord; a cover being connected to the insulating housing and operable into an open position and a closed position, the variable resistor being inaccessible when the cover is in the closed position, the inside of the cover being marked with indicia, said indicia being visible when the cover is in the open position; wherein the conversion adaptor matingly connects with the intermediate adaptor thereby electrically connecting the second terminals with the first terminals, the variable resistor of the intermediate adaptor setting output voltage.
