  • Patent number: 8847725
    Abstract: A temperature-dependent switch comprising a temperature-dependent switching mechanism having a snap-action disc, a housing having a lower part and an upper part which accommodates the switching mechanism, at least two stationary contacts provided on the inner surface of the upper part, each of which is connected to an outer connection, and a current transfer member arranged on the snap-action disc that is moved by said snap-action disc. The snap-action disc presses the current transfer member, in a temperature-dependent manner, against the two stationary contacts which serve as bearing areas for the current transfer member. A third bearing area for the current transfer member is provided on the inner surface. The current transfer member is an approximately round contact plate having on its surface facing the stationary contacts, a contact area closed in a circumferential direction around an axis of symmetry of the switch.

  • Publication number: 20130271258
    Abstract: A temperature-dependent switch has a temperature-dependent switching mechanism, which, depending on its temperature, opens or closes at least one switching contact, which is formed by two contact parts that are in contact with each other via their switching areas when the switch is closed. At least one contact part has a body made of resistance material and a top layer made of contact material and forming its switching area.

  • Patent number: 6714193
    Abstract: In an arrangement for processing digital video data there is provided for the most universal use of the arrangement and for a fast data exchange between components inside the arrangement. The arrangement utilizes at least one video data computer, at least one video data interface and at least one standard computer and/or one video hardware component, between which the video data can be exchanged through a fiber channel. The video data computer and the video interface(s) are controlled by at least one control computer via an Ethernet bus.
