摘要

The switch has several pole units, each with a pole head (3), a pole carrier, a contact system and a drive unit for initiating a switching movement in a movable contact of the system. Each pole head and pole carrier are fixed by a supporting device with a retaining plate. The supporting device has an insulation body formed as a single piece instead of two supporting units that are arranged adjacent to each other at a retaining wall.
