George Risk Industries 190-12-G Spdt Recessed Door Contact

Product Description

The George Risk Industries 190-12-G is a single-pole double-throw (SPDT) recessed door contact designed for installation in door frames and similar structural surfaces. With a 3/4-inch diameter housing machined from steel, this contact provides a durable, low-profile sensing solution for door position monitoring in security, access control, and alarm systems. The gray finish blends with standard frame materials. It ships as a single unit and is specified for applications requiring reliable switching action at the point of entry.

This recessed contact is suited for residential and light commercial door frame installations where a flush-mount profile is required. Typical applications include security panel integration, intrusion detection, and access control wiring. Electricians and low-voltage security installers specify recessed contacts like this model when surface-mount hardware is not acceptable due to aesthetic or code requirements. The SPDT configuration supports both normally open and normally closed circuit arrangements, making it adaptable to a range of control panel input types.

Key Features

• SPDT switching configuration supports normally open and normally closed wiring
• 3/4-inch diameter steel housing for durable, flush recessed installation
• Gray finish for low-visibility integration into door frame surfaces
• Single-unit packaging for individual replacement or new installation
• Low-profile recessed design eliminates surface-mount protrusion

Compatibility

Designed as an OEM-style recessed door contact for use in standard 3/4-inch diameter bored frame applications found in residential and light commercial security and access control systems.

Installation Notes

Installation is typically performed by a licensed electrician or certified low-voltage security technician. De-energize the alarm or access control panel before wiring connections. A 3/4-inch bit is required to bore the frame recess to proper depth. Follow all applicable NEC low-voltage wiring requirements and local authority having jurisdiction guidelines.
