Guide rings guide the switch handle when it is to be retracted. They compensate for the tolerances of the various components. For installation, guide rings can be inserted through the installation opening from the rear.

In contrast, cover rings are snapped in from the front. They cover tolerances and possible unevenness of the installation opening and are available for different material thicknesses of the panels.

Both the guide rings and the cover rings are available as a standard product or as a customised solution.
