A lighting unit for a household appliance, the lighting unit has a printed circuit board having a light-emitting means arranged on the printed circuit board, and a base for receiving the printed circuit board. The printed circuit board is arranged on a metallic holding part such that good thermally conductive contact is provided between the printed circuit board and the holding part, and the holding part is fastened on the base in such a way that good heat transfer is provided from the holding part to the base.

Lighting unit for a household appliance

A device for adjusting rotation angles, e.g. an electrical rotary switch (), has a stator () and a rotator () mounted on the stator (). The rotator () rotates between at least two rotational angle positions. The device has a magnet (), e.g. a permanent magnet, which can be moved by the rotor (), and a magnet field sensor (), e.g. a Hall sensor, which together with the magnet () produces a signal which corresponds to the rotational angle position. The stator () has a receptacle () open on one side and shaped like a pot, with the receptacle () forming a rotating bearing for the rotator (). The magnetic field sensor () is arranged in the receptacle () on the stator () and/or on a part which is mounted on the stator (), such that the stator is a mount for the magnet field sensor ().

Device for adjustment of rotation angles

An electric switch, in particular for a high load, such as a power switch. The switch has a contact system comprising a movable switching contact and at least one stationary contact. A movable actuation member, when moved, interacts with the switching contact for the purpose of switching the contact system. If appropriate, the switch may also have a movable locking means, which interacts with the actuation member in an interlocking manner. The actuation member is in operative connection with a lever in such a way that, when there is movement of the actuation member, the lever carries out a pivoting movement. The pivoting movement of the lever moves the switching contact for the purpose of switching and/or the locking means for the purpose of interlocking, in particular with increasing transformation of the displacement covered by the actuation member.

Electric switch

The invention relates to an electrical switch with a housing ( ). In the housing ( ) there is a contact system ( ), to which a switching effect can be applied by means of an actuating member ( ) which is arranged in an opening ( ) on the housing ( ) and partly protrudes out of the housing ( ). The part of the actuating member ( ) protruding out of the housing ( ) as well as the opening ( ) in the housing ( ) is covered by a cap ( ) allowing the movement of the actuating member ( ). The cap ( ) has a cover of a hard material and a sleeve-like part ( ) of a flexible material, designed in the manner of a bellows. The cover, designed essentially in the manner of a planar surface ( ), is arranged on the part of the actuating member ( ) protruding out of the opening ( ) in such a way that the actuating member ( ) can be moved via a side of the cover facing the user. One end of the sleeve-like part ( ) is fastened along a peripheral edge on the side of the planar surface ( ) of the cover facing away from the user. The other end of the sleeve-like part ( ) protrudes laterally beyond the surface ( ) of the cover, the protruding other end of the sleeve-like part ( ) being arranged on a region ( ) of the housing ( ) surrounding the opening ( ).

Electrical switch

A switch arrangement, in particular for domestic appliances, such as washing machines, dishwashers or the like has a housing (,) having at least one switching element which is located in the housing interior. At least one operating member is arranged on the housing, in order to act on the switching element in the sense of operating it. Furthermore, the housing has a supporting part, which has a holder for the operating member. The holder in the supporting part has an opening on the side facing the housing interior, which opening is associated with the switching element. A sealing element which is elastic in the movement direction of the operating member is fitted on the opening in the supporting part, between the switching element and the operating member, with the operating member acting on the switching element via the elastic sealing element. The sealing element is molded on the supporting part like a two-component part
