(under subclass 68) Subject matter wherein a variable resistor as there defined is combined with a switch, there being a linkage between the resistor and switch so that variation of the variable resistor over some portion of its resistance range causes operation of the switch to make and/or break an electrical circuit, or so that operation of the switch to make and/or break an electric circuit causes variation of the variable resistor over some portion of its resistance range.
(1) Note. Usually the subject matter of this subclass includes a variable resistor of no particular type together with a switch, the resistor operating the switch or vice versa.
