Elastically deformable resistor esp. for limiting or switching current

摘要

The resistor (1) has an electric resistor body (5) arranged between two contact terminals. The resistor body (5) is made of a connector material with a polymer matrix and an electrically conductive filler embedded in the matrix. The filer is in the form of a powder with particles whose average diameter is greater than 1 micron, preferably greater than 10 microns. The filler is a material which is harder and more resistant to oxidation than soot or silver. The resistor (1) is esp. used in a device for limiting and/or switching current. The resistor (1) is associated with a deforming arrangement (4) to elastically deform its resistor body (5). Upon a trigger signal (6) during operation of the device, the deforming arrangement (4) elastically changes the shape of the resistor body (5).
