.~ With current reversing (e.g., reversing rheostat)
DEFINITION
Classification: 338/78
(under subclass 68) Subject matter wherein a resistor or plurality of resistors as there defined is combined with or includes an electric switch in a common electric circuit, the switch being effective to reverse the electric current at the output terminals of the resistor with respect to the current applied at the input terminals.
(1) Note. Usually the resistor and switch have a common actuator.
