Description

1720-719: Product Overview

The Woodward 1720-719​ is a single-pole double-throw (SPDT) panel switch​ designed for industrial control systems​ (e.g., generator sets, engine controls, power distribution panels). As part of Woodward’s 1720 series, the 1720-719 is engineered to provide reliable circuit switching in harsh industrial environments, where durability and precision are critical.
The 1720-719’s primary function is to route electrical signals or power between two circuits​ using a single input terminal. It is commonly used to switch between different control modes (e.g., manual/automatic), activate/deactivate auxiliary systems, or redirect power to backup equipment. The switch’s SPDT configuration allows it to connect the input to one of two outputs, making it ideal for applications requiring binary decision-making (e.g., “on/off” or “normal/backup”).
The 1720-719 belongs to Woodward’s 1720 series of panel switches, a family of components designed for industrial control panels. The series is known for its robust construction​ (e.g., metal enclosures, sealed contacts) and compatibility with Woodward’s control ecosystems​ (e.g., 2301A series controllers, SPM-A synchronizers). The 1720-719 is typically mounted on the front panel of control cabinets, providing easy access for operators.

Core Features & Customer Value

The 1720-719’s design focuses on reliability​ and ease of use, delivering tangible benefits to engineers and operators:
  1. SPDT Configuration:
    • The switch’s SPDT design allows it to connect a single input to one of two outputs, enabling flexible circuit routing. For example, in a generator control panel, the 1720-719 can switch between “grid” and “backup” power sources, ensuring uninterrupted operation.
    • Customer Value: Reduces the need for multiple switches, simplifying panel design and lowering costs.
  2. Robust Construction:
    • The 1720-719 is built with a metal enclosure and silver-plated contacts, making it resistant to vibration, dust, and moisture. This durability ensures reliable operation in harsh industrial environments (e.g., power plants, marine vessels).
    • Customer Value: Minimizes downtime and maintenance costs, especially in remote or offshore sites where repairs are costly.
  3. Panel-Mount Design:
    • The switch is designed to be mounted on the front panel of control cabinets, providing easy access for operators. The compact size allows it to fit into crowded panels without compromising functionality.
    • Customer Value: Simplifies installation and maintenance, reducing the time required to modify or repair control panels.
  4. Compatibility with Woodward Ecosystem:
    • The 1720-719 is compatible with Woodward’s 1720 series panel switches and other control components (e.g., 2301A series controllers). This compatibility ensures seamless integration into existing Woodward systems, reducing the need for custom wiring or adapters.
    • Customer Value: Saves time and money during system upgrades or expansions.

Typical Applications

The 1720-719 is designed for industrial control applications​ where reliable circuit switching is required. Typical use cases include:
  1. Generator Control Panels:
    • In power plants, the 1720-719 is used to switch between “grid” and “backup” power sources for generator sets. This ensures that critical loads remain powered even if the primary grid fails.
  2. Engine Control Systems:
    • In marine or industrial engines, the 1720-719 switches between “manual” and “automatic” control modes. This allows operators to take manual control during maintenance or emergencies.
  3. Power Distribution Panels:
    • In factories or refineries, the 1720-719 redirects power to backup equipment (e.g., pumps, compressors) during maintenance or outages. This minimizes downtime and ensures continuous operation.
  4. Auxiliary Systems:
    • The 1720-719 activates/deactivates auxiliary systems (e.g., lighting, HVAC) in control panels. This simplifies operator interaction with the system.
