An electronic device for mounting on a support rail, has a housing, an electronic unit arranged in the housing, and an elastic contact element that serves in the electrically-conductive connection between the electronic unit and the support rail. The contact element has two contact legs, a connecting area connecting the contact legs to one another, and a contacting section connected to the connecting area for making contact with the electronic unit, and wherein when the electronic device is in the mounted state, the contact legs of the contact element make contact in a clamping manner with a leg of the support rail in-between. The contact element arranged ensures, with small size, good electrical and mechanical contacting of the support rail. The sides of the two contact legs facing one another form a short contact area. The first contact area on is sharp-edged, and the second contact area forms a swivel.

Electronic device and contact element for use in an electronic device

The invention relates to an assembly with an electrotechnical component on a carrier. A first electrical connecting line and a second electrical connecting line going to the electrotechnical component are provided on or in the carrier. The electrotechnical component comprises a first connection and a second connection. The first connection is attached on the carrier by a thermally softenable solder material to the first electrical power supply line, and the second connection is attached on the carrier by a thermally softenable solder material to the second electrical power supply line. A first electrical signal line to the electrotechnical component is provided on or in the carrier. The assembly furthermore comprises a mechanical prestressing, which in the event that the solder material is softened can displace the electrotechnical component on the surface substantially in a parallel plane to the carrier or orthogonally to the carrier.

An overvoltage protector having a housing and at least one overvoltage limiter arranged in the housing, especially a gas-filled surge arrester (), a suppressor diode () or a varistor. The functional ability and the state of the overvoltage protector can be controlled during operation by associating a monitoring component with the overvoltage limiter which detects a current (i) flowing over the overvoltage limiter component, and by providing an evaluation unit that evaluates the signal of the monitoring component.

Overvoltage protector

The object of the invention is a thermal overload protection device () for protecting an electric component (), in particular an electronic component, wherein the overload protection device () has a short-circuit unit () for short-circuiting connections () of the component (), and an actuating member () actuating the short-circuit unit () in a temperature sensitive manner. According to the invention it is provided that the short-circuit unit () is attached to a circuit path support () in at least one area (), and is supported in at least another area () on the component () disposed on the circuit path support () via the actuating unit (), and/or at least one of the circuit paths () contacting one of the connections () to be short-circuited. The invention further relates to a respective arrangement () having a circuit path support (), at least one component () disposed thereupon, and at least one assigned overload protection device ().
