George Risk Industries Inc. 4402-A Aluminum Spdt Contact

Product Description

The GEORGE RISK INDUSTRIES INC. 4402-A is an aluminum single-pole double-throw (SPDT) contact assembly with an armored cable. SPDT contacts are switching devices used in security, access control, and building automation systems to detect the open or closed state of a door, window, or access point. The armored cable construction provides mechanical protection for the wiring, making this unit suitable for installations where the cable may be exposed to physical stress or tamper attempts. This type of contact is typically installed by security technicians, electricians, or low-voltage control specialists.

The 4402-A is suited for use in commercial and residential applications where a protected, reliable switching contact is required. Common installation scenarios include door and window monitoring in security alarm systems, access control panels, and building automation control loops. The armored cable design is particularly useful in high-traffic or industrial environments where standard unprotected wiring may be vulnerable to damage. This part is sold individually as a single unit.

Key Features

• Single-pole double-throw (SPDT) switching configuration for flexible circuit integration
• Aluminum construction for lightweight durability
• Armored cable provides mechanical protection against physical damage and tampering
• Suitable for door, window, and access point monitoring applications
• Sold as an individual unit (each)

Compatibility

Designed as an OEM-style replacement or direct installation contact for security alarm, access control, and building automation systems requiring an SPDT switching contact with armored cable protection.

Installation Notes

Installation of this contact should be performed by a licensed electrician or qualified low-voltage security technician in accordance with applicable NEC requirements for the installation location. De-energize the circuit and disable the alarm or control panel before wiring the contact. Ensure the armored cable is properly supported and routed to avoid sharp bends that could compromise the cable jacket or internal conductors.
