Abstract
A switching resistor for an electric switching device having an electrically conductive resistive material. The resistive material is a resistive material on a synthetic material basis.
Claims14
A switching resistor for an electric switching device, comprising:
- an electrically conductive resistive material based on a synthetic material;
- said resistive material including a non-conductive synthetic material, a conductive additive mixed with said synthetic material with a super-percolative degree of filling, and at least one macroscopic filler having a high electrical resistance;
- and
- said resistive material having a resistance value being set by an amount of said filler mixed with said synthetic material.
