Dormakaba Rci 960NMO28 Narrow Mortise Key Switch

Product Description

The DORMAKABA USA INC. / RCI 960NMO28 is a narrow mortise key switch designed for access control and door security applications. Mortise key switches provide a manual, keyed override or activation point for electrically controlled door hardware, allowing authorized personnel to operate locking devices, electric strikes, or access control circuits directly. This switch is built for installation in standard narrow mortise cutouts and is typically installed by locksmiths, access control technicians, or commercial door hardware professionals.

This key switch is suited for commercial access control systems where a flush, mortise-style mounting is required. Narrow mortise formats fit doors and frames with limited edge clearance, making this switch appropriate for aluminum storefront doors, narrow stile doors, and similar commercial door assemblies. It is commonly used in conjunction with electric strikes, magnetic locks, or access control panels to provide a local keyed activation or shunt point.
