Abstract

An electrical switch is disclosed, especially a circuit breaker. In addition, a method for improving such a switch is also disclosed. In order to protect an electrical switch in an especially simple manner from contamination and/or damage by erosion materials, it is proposed to cover a few or all functional parts of the switch at least partly with a protective material, wherein the protective material involves a viscous, temperature-resistant mass.
