Abstract

A switch includes a diverter contact; a primary fixed contact; and a secondary fixed contact. The switch additionally includes a primary movable contact configured to be pivoted, relative to the diverter contact and the primary fixed contact, about a pivot axis between a first end position and a second end position. In the first end position, the primary movable contact bears by a first contact point against the diverter contact and by a second contact point against the primary fixed contact. The switch further includes a secondary movable contact configured to be pivoted, relative to the diverter contact and the secondary fixed contact, about the pivot axis between a first end position and a second end position. In the first end position the secondary movable contact bears by a third contact point against the diverter contact and by a fourth contact point against the secondary fixed contact.
