Abstract

A switchgear, for low-voltage switching units with a linearly-displaceable contact support, includes a case-like housing with guide grooves, running in the direction of travel of the contact support, in the housing side walls thereof. Suitable projections on the side of the contact support, engage in the grooves, whereby the linear travel of the contact support is achieved. Pivoting contacts are arranged on the contact support as displaceable switch contacts.
