摘要:
A touch contact switch has a sensor key or button with a spatially extended, electrically conductive foam or flexible plastic or rubber body. The switch is operated by contact or approach. The sensor button essentially forms one pole of a capacitor and is electrically connected to an evaluating circuit of the touch contact switch, wherein switching is initiated as a result of a capacitance change in consequence of approach or contact. The sensor button can be bonded directly on a mounting plate of the associated electrical evaluating circuit or can be engaged by a pin or the like. The body can be flush to the underside of a cover, which forms or contains the contact surface. The body can include an opening along the longitudinal axis in which is insertable a LED.

An arrangement for the control of electrically controllable appliances, particularly electric cookers proposes for each cooking point an operating element magnetically held in contactless manner on the top or front of a plate, e.g. a glass ceramic plate. Below or behind the plate is located a magnet, which magnetically secures the operating element, which can in this position be rotated in contactless manner sensors are operated, which are used for changing the control of the cooking point. Both the control and the fixing of the operating element take place in contactless manner. The plate requires no openings, passages, depressions, etc. The operating elements can be removed on overcoming the magnetic holding force. This removal can be utilized for the complete disconnection of the cooker.

A cooktop with a ceramic glass panel has a panel portion with a first indicia set for selection of a burner and a second indicia set for selection of a power level to the selected burner. Each set of indicia is associated with switches for input to a control circuit in response to manipulation by a user. In addition, each indicia set includes a display interactive with the manipulation of the other indicia set. Preferably, the control circuit includes a processor for responding only to a sequential manipulation of an indicia from the first set indicia set and a sequential manipulation of an indicia from the second set within a predetermined time period.

An appliance control protection apparatus for a glass ceramic cooktop is constructed with a double wall housing and a low voltage cooling fan. The double wall housing is comprised of a first inner wall and a outer wall and prevents the transfer of heat from the heating elements in a glass ceramic cooktop towards the electronic control unit. The first inner wall is adhered to the underside of the ceramic glass panel of the cooktop and the outer wall snaps into position over the first wall, resulting in a space therebetween for insulation. Additionally, the control housing is provided with a low voltage fan that convects heat away from hot spots formed on the electronic control unit toward other components within the control housing. The low voltage fan operates in response to certain operating temperatures within the control housing as detected by a heat sensor.

A method and apparatus for illuminating a heated area on a cooktop panel includes a light ring peripherally aligned about a burner under the cooktop panel, a gasket for resiliently retaining the tube beneath the cooktop panel and a support for resiliently engaging the gasket against the panel. Preferably, the light ring is a tube recessed within the gasket to avoid direct contact with the cooktop panel surface. The gasket may also restrict illumination to a channel portion of the gasket. Alternatively, the tube can be coated to avoid illumination in directions other than the area exposed to the panel. The gasket forms a convenient masking tool for delineating the surface area of the tube that is to be exposed while shielding other exterior surfaces of the tube. Both the illuminator and the method for illuminating the burner are simplified when the gasket includes a support flange beneath the tube retaining socket.

An electrical switching device includes a switching device socket and terminals. The device also includes a snap-action switch with at least one catch spring. The catch spring carries at least one switching contact stud. The snap-action switch is trippable by a thermobimetal. For thermal influencing the thermobimetal, a heating device with a heating resistor mounted on a metal support is provided. The metal support can be made from a steel plate carrying an electrically insulating layer made from glass. An extensive heating resistor is provided on the insulating glass.
摘要:
A cooktop having a flat glass ceramic plate and a plurality of rails independently attached to the bottom surface of the glass ceramic plate. The rails are configured to be received in a cutout in a countertop and are not connected to each other at the corners. The bottom of the cooktop is enclosed by a rough in-box consisting of a primary U-shaped cover and two independent end covers.
