Sdc 701NUL1R Key Switch

Product Description

The SDC - SECURITY DOOR CONTROLS 701NUL1R is a key switch designed for access control applications in commercial and institutional door hardware systems. Key switches provide a simple, reliable method of controlling electric locks, magnetic locks, or door release circuits through a physical key-operated mechanism. This unit is a single-piece component sold individually and is typically installed by licensed locksmiths, security integrators, or commercial electricians performing door access control work.

Key switches in the 701N series are suited for commercial access control installations where a physical key must authorize door release or locking. Typical applications include secured entry points in office buildings, schools, hospitals, and light industrial facilities. The 630 finish designation indicates a satin stainless steel appearance, making it appropriate for installations where a clean, durable surface finish is required.
