Sdc 701U Key Switch Momentary Spdt 10 Amp

Product Description

The SDC - SECURITY DOOR CONTROLS 701U is a momentary single-pole double-throw (SPDT) key switch rated at 10 amps. It is designed for access control and door security applications where a keyed operator is required to momentarily actuate an electrical circuit. The 701U ships in a 630 finish, making it suitable for installation in commercial and institutional environments where consistent hardware aesthetics matter. Security and low-voltage access control technicians are the primary installers of this device.

The 701U is used in commercial door hardware and access control systems where a physical key is required to trigger a relay, release mechanism, or other controlled circuit. Typical install scenarios include electric strike or magnetic lock activation, elevator call stations, and gate control panels. The momentary action means the output contact is only active while the key is held in position, which suits latching relay circuits and momentary release configurations.

Key Features

• Momentary SPDT switching action for use with latching or pulsed control circuits
• 10 amp contact rating provides capacity for direct relay or load switching
• 630 satin stainless finish for corrosion resistance and aesthetic compatibility with commercial hardware
• Keyed operation restricts unauthorized actuation
• Single-unit packaging suitable for individual replacement or new installation

Compatibility

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

Installation Notes

Installation is typically performed by a licensed access control or low-voltage technician. De-energize all associated control circuits before wiring the switch. Verify that the load connected to the switch contacts does not exceed the 10 amp rating. Follow NEC Article 725 requirements for Class 2 or Class 3 control wiring as applicable to the installation.
