Abstract
Abstract An electrical switching device has a housing composed of an electrically conductive material, at least one conductor plate having a region of an electrically conductive material and arranged in the housing, plug connection means extending from the housing in a sealed manner, and an element for electrically conductive connection of the conductor plate with the housing. The element for electrically conductive connection includes a mechanically prestressed spring element. The spring element has one end abutting against the conductor plate in the region of an electrically conductive material and another end fixedly connected with the housing.
