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 refrigeration device is provided that includes two housing parts in the form of a body and a door that together delimit an interior. A seal is fastened to one of the housing parts and sealingly contacts the other housing part when the door is closed and a drive element is arranged to drive the door from the closed position into an open position. A sensor detects a movement of the door and a control circuit coupled to the sensor activates the drive element when a movement of the door is detected.

Refrigeration device comprising a door-opening aid

The invention relates to a measuring apparatus for measuring a measurement variable of a fluid, in particular a sensor, such as a pressure sensor or a travel sensor. The measuring apparatus has a housing, a diaphragm which is arranged in and/or on the housing and an elastic element, which is designed in the manner of a leaf spring, for restoring the diaphragm. A signal transmitter is operatively connected to the diaphragm and/or to the elastic element, and a signal receiver interacts with the signal transmitter. Structures for providing reinforcement are arranged in the edge region and/or in the center of the elastic element.

Sensor

The invention relates to an electrical switch, in particular in the form of a microswitch and/or snap-action switch, having a housing which comprises a base and a cover. The switch has a contact system, which comprises a movable switching contact and at least one stationary contact. Furthermore, the switch has a moving operating member for switching of the contact system. The cover is mounted on the base such that it can move, and the operating member is formed by the cover.

Electrical switch

A process and a device are provided for ascertaining the rotation of a liquid spray arm for a domestic appliance. Lighting means serves as a light transmitter and a photoreceiver serves as a light receiver. The lighting means and the photoreceiver are assigned a light-conducting element. At a first location of the light-conducting element, at least some light emitted from the lighting means is coupled to a path so that the light is guided in the light-conducting element by total reflection. At a second location of the light-conducting element that spaced apart from the first location in the direction of propagation of the light, the light guided in the light-conducting element is coupled out of the path so that the light is received by the photoreceiver. The intensity of the light received by the photoreceiver is evaluated by an evaluation circuit with respect to the rotation of the spray arm.

The invention relates to a power breaker for switching electrical loads having a parallelepipedal shape having four longitudinal sides lying in the longitudinal direction (LQ) of the parallelepiped, a first transverse side and an opposing second transverse side, an electromagnetic coil having a longitudinal axis (LS), an input connection, an output connection, and a moving contact path that is electrically connected to the input connection or the output connection. The invention also relates to power supply assembly arrangement for switching an electrical current between an external power supply line and at least one load where the moving contact path and the coil are arranged longitudinally parallel to one another in the longitudinal direction (LQ) of the parallelepipedal shape.

Power breaker and arrangement for switching electrical currents

The invention relates to a path and/or position measuring device () comprising a magnet () and a sensor () detecting the magnetic field intensity. The magnet () and/or the sensor () co-operate with a movable element (), it being possible for a relative movement between the sensor () and the magnet () to be brought about by means of the movable element (). Furthermore, the magnet () is formed in such a way that the magnetic field intensity varies along an axis () of the magnet () and is not constant. The relative movement is substantially in the direction of this axis () of the magnet (). The path and/or the position of the movable element () can be determined on the basis of the magnetic field intensity detected by the sensor ().

Device for measuring paths and/or positions

A sensor for detecting a rupture or length change in a belt. The sensor has a movable transmission element operatively connected to the belt, that acts on an electrical switch having a contact system in the event of a length change or rupture of the belt. The contact system comprises a switching contact with a contact surface arranged on a first end, and an associated fixed contact. The transmission element acts on the second end of the leaf spring. A limb extends approximately from the first end of the leaf spring in the direction of the second end, and a further limb extends from the second end of the leaf spring in the direction of the first end. The free ends of the two limbs are clamped offset from one another on a carrier part of the switch, such that the switching contact switches over in a bistable manner.

Sensor for detecting belt rupture

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.
