Abstract

A retrofittable earthling device includes a first contact arranged on the switching device and a second contact arranged on the module frame by way of a contact carrier. They are adjacently spring-mounted, during the movement of the switching device from its point of separation into its operating position. In order to relieve the contact carrier, in one such device, of electrodynamic effects and thus to make the same easy to assemble, the contact carrier includes a first partial region for connecting an earthing device, and a second partial region which can be connected to the second contact, in addition to a contact strip connecting the two partial regions. The first partial region can be connected to the module frame in a fixed manner and the second partial region is held on the rear wall of the module frame, with transversal play in relation to the direction of movement of the switching device.
