OVERVIEW CM-84 & CM-85 Series “Side Load" COLUMN switches with 3" (75mm) wide activation plate offer greater user convenience and lower installation costs by providing a single activation device in place of two high / low switches, as required by a growing number of building codes across North America. These COLUMNswitches feature solid aluminum or stainless steel construction and are available in a range of finishes. Deeper design accommodates DPDT switches and Kinetic switches. The sturdy backplate design allows column switches to be mounted to narrow curtain walls, or span lites of glass.
