at least one sensor-readable element configured for contactless-interaction with the contactless-type sensor;
the at least one sensor-readable element of the input control module being configured for movement into a plurality of different positions relative to the at least one contactless-type sensor of the processor module disposed inside the housing, whereby responsive to the movement of the at least one sensor-readable element into the plurality of different positions relative to the at least one contactless-type sensor, the contactless-type sensor is configured to sense a plurality of different readings from the sensor-readable element, and, the processor module is configured for controlling the electrical appliance to operate in a plurality of different operational modes by reference to the plurality of different readings sensed by the contactless-type sensor;
wherein the input control module further includes a first member and a second member that are rotatably connected together and wherein a detent mechanism is disposed between the first and second members to provide controlled incremental rotatable movement of the first member about the second member, and, the at least one contactless-type sensor being communicably-connected with the processor module so as to provide the processor module with readings indicative of the plurality of rotational positions of the first member relative to the second member.

2. The control system as claimed in claim 1 wherein the at least one sensor-readable element is configured for at least one of rotational, sliding, swiveling and depressible movement.

3. The control system as claimed in claim 1 wherein the input control module includes a control knob.

4. The control system as claimed in claim 1 wherein the second member is depressible relative to the first member.

5. The control system as claimed in claim 1 wherein the input control module includes a plurality of first members that are rotatable about the second member.

6. The control system as claimed in claim 1 wherein the at least one sensor-readable element is disposed on at least one of the first and second members whereby the at least one contactless-type sensor is configured for sensing a plurality of readings in response to at least one of rotational movement of the first member relative to the second member and depressible movement of the second member relative to the first member.

7. The control system as claimed in claim 1 wherein the at least one sensor-readable element is arranged in a ring-shaped configuration.

8. The control system as claimed in claim 1 wherein the processor module includes a printed circuit board having at least one microprocessor integrated circuit chip operably-connected with the at least one contactless-type sensor.

11. The control system as claimed in claim 1 wherein the attachment element is configured for releasably attaching the input control module to the outer surface of the housing by way of magnetic force.

12. The control system as claimed in claim 1 wherein the input control module is configured for releasable attachment to an outer surface of the housing comprising an electronic display panel.

13. The control system as claimed in claim 12 wherein the electronic display panel includes a touch-sensitive electronic display panel.

14. A control knob for use in controlling operation of an electrical appliance, the electrical appliance including a housing and a processor module having at least one contactless-type sensor operably-connected thereto disposed inside the housing, the control knob including:
an attachment element configured for releasably attaching the control knob to an outer surface of the housing; and
at least one sensor-readable element configured for contactless-interaction with the contactless-type sensor;
the at least one sensor-readable element of the control knob being configured for movement into a plurality of different positions relative to the at least one contactless-type sensor of the processor module disposed inside the housing, whereby responsive to the movement of the at least one sensor-readable element into the plurality of different positions relative to the at least one contactless-type sensor, the contactless-type sensor is configured to sense a plurality of different readings from the sensor-readable element, and, the processor module is configured for controlling the electrical appliance to operate in a plurality of different operational modes by reference to the plurality of different readings sensed by the contactless-type sensor;
wherein the input control module further includes a first member and a second member that are rotatably connected together and wherein a detent mechanism is disposed between the first and second members to provide controlled incremental rotatable movement of the first member about the second member, and, the at least one contact-less type sensor being communicably-connected with the processor module so as to provide the processor module with readings indicative of the plurality of rotational positions of the first member relative to the second member.

15. An electrical appliance operably-controllable by an input control module:
the electrical appliance including a housing and a processor module having at least one contactless-type sensor operably-connected thereto disposed inside the housing;
the input control module, including:
