A knob assembly with a display that displays information such as power level and a timer time, and a cooking apparatus including a knob assembly are provided. The knob assembly may include a knob coupled to an adjustment shaft configured to adjust power level and a knob ring configured to surround a periphery of the knob, configured to be rotatable independent of the knob, and provided with a display. The display may be provided at the knob ring, and information may be displayed on the display so that a user may easily manipulate the knob assembly.

A knob assembly includes a front panel, a knob located at a front side of the front panel and configured to rotate based on operation by a user, a knob shaft that is coupled to the knob and that extends through the front panel, a supporting pipe that receives the knob shaft and that supports the knob shaft, the supporting pipe being configured to maintain a position relative to the front panel, a valve configured to control supply of gas to the appliance, a valve shaft connected to the valve and configured to control the valve to adjust a flow rate of gas based on rotation of the valve shaft, and a joint that couples the knob shaft to the valve shaft and that is configured to transfer at least one of a rotational motion or a linear motion of the knob shaft to the valve shaft.

A lighting control switch harness includes a plurality of elements each including a body for a respective gas tap, one or more light sources, and a printed circuit. A first switch includes a first member couplable to a mobile stem of the gas tap for integrally rotating therewith and taking contacts of the first switch towards one another. A second switch includes a second member couplable to the stem of the tap for translating parallelly thereto and taking contacts of the second switch towards one another. The elements are connected to one another only by a first wire connected to a first contact of the second switch of each element, a second wire connected to a second contact of the first switch of each element, and a third wire connected to a second contact of the second switch of each element and to the printed circuit.

A switch device and a cooking device having a switch device. The switch device may include a first switch configured to be opened or closed based on contact or non-contact between a first blade and a second blade; a second switch configured to be opened and closed based on contact or non-contact between a third blade and a fourth blade; a housing that accommodates the first switch and the second switch therein; and an actuator disposed in the housing and actuated to selectively open and close the first switch and the second switch.

The present invention provides a smart monocontrol cartridge for taps, a smart tap that incorporates said cartridge, and a smart system that incorporates said tap, the monocontrol cartridge comprising a based with a lower end, an upper end for coupling to ceramic discs and an intermediate portion in which a recess is defined in which an electronic module is coupled that is configured to house indirect temperature detection means configured to detect the temperature in the mixed water channel and electronic means configured to calculate the real temperature in the mixed water channel based on an indirect temperature detection, the indirect temperature detection means being in data communication with the electronic means; and wherein a flexible cable is coupled between the electronic module and the cam.

A knob assembly includes a front panel, a knob located at a front side of the front panel and configured to rotate based on operation by a user, a knob shaft that is coupled to the knob and that extends through the front panel, a supporting pipe that receives the knob shaft and that supports the knob shaft, the supporting pipe being configured to maintain a position relative to the front panel, a valve configured to control supply of gas to the appliance, a valve shaft connected to the valve and configured to control the valve to adjust a flow rate of gas based on rotation of the valve shaft, and a joint that couples the knob shaft to the valve shaft and that is configured to transfer at least one of a rotational motion or a linear motion of the knob shaft to the valve shaft.

A limit switch assembly for a rising-stem valve includes an operating lever actuator element mounted to an outer end of an actuator arm. An electrical switch mounted adjacent the outer end has an operating lever. When the actuator arm is in an outward position, the operating lever actuator element retains the operating lever in a first position wherein the electrical switch is in a first state, and when the actuator arm is in an inward position the operating lever is in a second position wherein the electrical switch is in a second state. An adjustment nut is mounted to the outer end adjacent the operating lever actuator element, and the operating lever actuator element and the adjustment nut are configured to be adjusted along a longitude of the actuator arm to change a distance the operating lever actuator element must travel to move the operating lever into the first position.

A limit switch assembly, for a rising-stem valve having a stem with a diameter and a groove marking a desired stem position, includes an actuator arm having an inner end and an outer end. The inner end of the actuator arm forms a follower. A radius washer is mounted to the outer end of the actuator arm. An electrical switch has an operating lever and is mounted adjacent to the outer end of the actuating arm such that when the actuator arm is in an outward position the radius washer moves the operating lever, operating the electrical switch. When the actuator arm is in an inward position the radius washer does not move the operating lever and the electrical switch is not operated. A bias spring biases the actuating arm toward the inward position.

Provided is a multifunction switch (1) having a switching function for an electrical contact switch and a switching function for a mechanical element. The multifunction switch (1) includes a swingable control body (20) having a control pin (22), a movable contact (31) coming into contact with the control pin (22), and a movable element (40) having the control pin (22) running therethrough and swingably supported. With the control pin (22) being swung, the movable contact (31) is pressed by the control pin (22) to come into contact with a fixed contact (32) and the movable element (40) is swung by the control pin (22) to implement mechanical switching for an additional element.
