Provided is an illumination system of a cooking appliance that includes at least one burner and an associated knob. The system comprises an electric circuit associated with the knob, with a display device in a second electrical branch that lights up when an electric current with a minimum value circulates through the second electrical branch. Activation means in a first electrical branch is operated by means of turning the knob. Both the first and second electrical branches are connected in parallel. Acting on the knob causes a change in voltage drop in the first and second electrical branches, and the illumination system is configured to control the electric current circulating through the display device depending on said voltage drop.

The present invention relates to an illuminated releasable rotary knob for use in an appliance, in particular in a cooking appliance comprising a panel which includes a regulator shaft; and a control unit which has an electrical connection for supplying electric power. The knob comprises non-transparent handle, a hub for releasably receiving the shaft, a cavity, an illuminating device for illuminating the cavity, a connector for receiving the electrical connection and a transparent indicator which receives the illumination from the cavity.

A switch for controlling an electrical appliance has a switch housing, an actuation element, a display, and a microprocessor disposed in the switch housing. The actuation element can activate an identifier through the display, which identifier is determined by the microprocessor. Selection of an appropriate system state and an associated maximum value is effected by again actuating the actuation element, specifically while the corresponding identifier associated with this system state is active or displayed. Reaching or exceeding the maximum value is indicated by a signal that is produced by the microprocessor. The microprocessor can optionally be activated once again for a reset mode and/or for a change mode.

A switch assembly and method of using same comprises a switch assembly for operating a power take off unit on a lawn tractor, the switch assembly further includes a housing supporting a selectively locatable activation knob facilitated by an actuation assembly and an internal switch arrangement coupled to a printed circuit board within the housing. The internal switch arrangement comprises a microcontroller and switch for determining the relative position of the selectively locatable activation knob and provides a digital output signal for enabling or disabling a power take off unit based on the digital output signal.

Electrical switches with label access mechanisms. In one aspect, a rocker switch with a translucent cover presents an elongated aperture, or slot, for insertion or removal of a label. In embodiments, the slot is arranged on an upper, or top surface of the cover, or on a side surface of the cover. In embodiments, more than one slot is provided. A hinge is provided on the cover of a rocker assembly, the hinge enabling the cover to rotate relative to the rocker assembly for access, insertion, and removal of interchangeable labels.
