Abstract: A switching and protection device for high-voltage onboard electrical systems having a DC-voltage switch and a fuse, wherein the DC-voltage switch includes a housing, at least two fixed contacts, and a bridge designed to be movable with respect to the fixed contacts, wherein the bridge is formed from an electric insulator, wherein two contacts are arranged on the bridge such that, during a movement of the bridge in the direction of the fixed contacts, the two contacts make contact with the fixed contacts, wherein the two contacts arranged on the bridge are electrically connected to each other via the fuse.

Abstract: A DC voltage switch for high-voltage on-board electrical systems having a housing, at least two stationary contacts, and a moving contact, wherein, in each case, a first contact region of the stationary contacts is routed out of the housing and, in each case, a second contact region of the stationary contacts is arranged in a switching chamber of the housing with the moving contact, wherein the housing is hermetically encapsulated, wherein a cooling chamber which is separated from the switching chamber by a partition wall is arranged above the switching chamber, wherein the partition wall has at least one outlet opening and at least one inlet opening.

Abstract: The invention discloses an LED luminaire, in the case of which an LED module is applied to the luminaire body such that the height of the luminaire body and the LED module is ?8 mm and the luminaire body at least partially forms the heat sink for the LED module. In this case, LED modules having power ratings of ?3 watts are used. LED operating devices can be used for voltage supply purposes which form an outer face section of an arrangement comprising a luminaire body and an LED operating device, the total height of the luminaire body and LED operating device being ?10 mm, and the LED operating device preferably being cooled via the luminaire body.
