We report on the realization of one-dimensional topological states of matter within electrical circuits. At the example of the Su-Schrieffer-Heeger circuit, we elaborate how topological edge states and domain walls manifest themselves in the impedance read-out of a periodic electrical circuit. We further outline prospective generalizations and applications.
