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 bezel assembly for a control panel of a cooking appliance. The bezel assembly includes a body portion that extends along an axis and includes a body exterior surface and a body interior surface. The body interior surface defines a channel for accommodating components of a control knob assembly. A rim portion extends along the axis and includes a rim exterior surface and a rim interior surface. The rim interior surface defines an opening for accommodating components of the control knob assembly. A plurality of cam fingers are configured to be articulated radially outwardly for interfacing with an interior surface of the control panel.

The operating device, in particular for a vehicle component, is provided with a rotary operating element (18), which can be rotated about a rotation axis (20) and is formed as a plastic injection-molded part, which is produced in a molding die (48) having a die separation plane (46), and with a bearing unit (12), on which the rotary operating element (18) is mounted such that it can rotate about the rotation axis (20). The bearing unit (12) has a first bearing element (14), which is formed as a plastic injection-molded part, which is produced in a molding die (28) having a die separation plane (34). The first bearing element (14) has a bearing surface (26), which extends in a radial plane to the rotation axis (20) and concentrically to same, and the rotary operating element (18) has a contact surface (36), which bears against the bearing surface (26) and likewise extends in a radial plane to the rotation axis (20) and concentrically to same. Either the bearing surface (26) of the first bearing element (14) or the contact surface (36) of the rotary operating element (18) is arranged outside the die separation plane (34; 46) of the injection-molding die (28; 48) for said relevant element (14; 18), and the other of the two surfaces (26; 36) is arranged in the die separation plane (34; 46) of the injection-molding die (28; 48) of said relevant element (14; 18).

A control knob comprises an encoder assembly configured to convert rotary and axial input movement into electronic signals, and a knob assembly attached to the encoder assembly and configured to be operated by a user, wherein the encoder assembly comprises a shaft encoder having a shaft that is configured to be rotated around a rotation axis and to be moved axially along the rotation axis, the knob assembly comprises an outer knob element configured to be operated by a user, the knob assembly further comprises a bush defining a cylindrical cavity inside the outer knob element, wherein the bush has an opening towards a first side of the outer knob element facing towards the encoder assembly, the knob assembly further comprises a driver element extending into the bush from a second side opposite the first side.

A control device, includes a switch (2) with a rotary control rod (20) having a diametrical slot (21) which extends in a plane of reference (P), a molded plastic knob (3) which includes a housing receiving the control rod, the housing including two flexible fingers (31, 32) which are diametrically opposed and provided so as to be resilient radially inward, and two fixed fingers (33, 34) which are diametrically opposed and are connected together via a connecting wall (35) which extends along the plane (P), the connecting wall (35) being received in the diametric slot without any play in order to immobilize the knob in relation to the control rod in a direction (Y) perpendicular to the plane (P), the two flexible fingers holding the knob along the axis (A) by friction or by mechanical or spring-assisted blocking.

A switch, a power conversion apparatus, and a power supply system. The power supply system includes a control unit, a switch, a direct current source, and a power conversion unit. The switch is electrically connected between the direct current source and the power conversion unit, and the control unit is configured to send a switch-off signal to the switch when a fault occurs on the direct current source or the power conversion unit. The switch includes a contact component, a trip-free structure, and a knob that are sequentially disposed in a stacked manner in a first direction. A trip unit of the trip-free structure is configured to receive the switch-off signal, to unlock the trip unit from the cradle. The cradle drives the connecting rod structure to move, to separate the moving contact from the fixed contact.
