Abstract: The switch has at least two contact pieces (1,2) and at least one light arc rail (3) adjacent to and connected to at least one contact piece, which does not lie in the current path with the contacts closed and which produces a light arc (4) from the contact piece to the rail when the contact pieces are opened. The light arc rail consists at least partly of positive temperature coefficient conductor material and/or is connected via a PTC conductor (5) to an adjacent contact piece. An Independent claim is also included for a switch arrangement.

Abstract: The invention concerns an improved joining method for joining two parts (1 and 2) by means of a joining material layer (3). By means of contacts (4 and 5), a voltage is applied to a PTC polymer material layer in the joining material (3) from an energy supply (6) via an external electric circuit. The PTC effect leads to automatic uniform distribution of the Joulean heat loss and to uniform two-dimensional melting when the joint is being produced.

Abstract: The invention relates to an apparatus for limiting an electrical current by using a PTC resistor being monitored by a monitor circuit. According to the invention, the monitor circuit issues a signal only after detecting the status of the PTC resistor for a defined time period after a PTC resistance change.

Abstract: The invention relates to a novel method of producing a resistor device comprising a PTC-polymer element 2 and a varistor element 4. Both elements are moulded in a common moulding process using one common mould. Preferred is co-injection moulding. The invention further relates to the resistor device thus produced and a current limit means including this resistor device and a switch (fig. 4).

Abstract: The invention relates to an electrical device with a PTC polymer element having a constriction. The constriction defines a web extending in a main current direction over a length longer than in the prior art, namely longer than 5 mm, preferably longer than 15 mm. Further, the aperture angle of the PTC polymer material a t the ends of the web is larger than 100.degree.. A preferred choice of material i s given, further. The invention achieves very high voltage-withstand capabilities.
