Sdc 712ULT Momentary Dpdt Key Switch

Product Description

The SDC - SECURITY DOOR CONTROLS 712ULT is a momentary-action, double-pole double-throw (DPDT) key switch designed for access control and door security applications. Momentary-action means the circuit activates only while the key is held in position and returns to its default state upon release. The DPDT configuration provides two independent switched circuits in a single unit, giving installers flexibility for more complex control logic. This switch is finished in satin chrome (630), making it suitable for installations where hardware finish consistency is required. Access control technicians and security system integrators are the primary trade professionals who install this device.

The 712ULT is used in commercial and residential access control systems where a keyed operator is required to trigger or release an electric door strike, magnetic lock, or related entry hardware. The momentary DPDT configuration suits applications that require momentary pulse signals to access control panels or relay inputs. Typical installation locations include building entry points, secure room access, elevator control panels, and gate operator systems where unauthorized operation must be prevented.

Key Features

• Momentary-action operation returns switch to neutral state when key is released
• Double-pole double-throw (DPDT) contact configuration for versatile circuit switching
• 630 satin chrome finish for consistent hardware aesthetics in commercial installations
• Sold as individual unit for single-point replacement or new installation
• Keyed operation restricts switch actuation to authorized personnel only

Compatibility

Designed as an OEM-style replacement or new-installation key switch for commercial and residential access control systems requiring a momentary DPDT keyed input device.

Installation Notes

Installation should be performed by a licensed access control or low-voltage technician familiar with DPDT switching circuits and local electrical codes. De-energize all connected access control hardware and lock out power before wiring the switch. Follow NEC low-voltage wiring requirements and the door hardware manufacturer guidelines for signal input wiring. Do not use this switch as a primary power disconnect for line-voltage circuits.
