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.
Claims18
An electrical switch, comprising:
- functional parts relevant to a function of the switch, especially the opening function, surfaces of a few or of all of the functional parts being covered at least partly with a protective material to protect against at least one of contamination and damage by erosion materials, wherein the protective material involves a viscous, temperature-resistant mass.
A method for improving an electrical switch, comprising:
- covering surfaces, of a few or all of the functional parts of the electrical switch relevant to a function of the switch, at least partly with a protective material to protect against at least one of contamination and damage by erosion materials, wherein the protective material involves a viscous, temperature-resistant mass.
