Fairchild 15442EJT Positive Bias Relay

Fairchild 15442EJT Positive Bias Relay is a Fairchild-brand electro-mechanical switch identified by the 15442EJT part number, and is sometimes described in catalogs as the Fairchild Model 15 Positive Bias Relay. As a relay, it is designed to control a circuit by energizing an internal coil to move one or more contacts, providing isolation between the control circuit and the switched circuit. The "positive bias" label indicates a particular biasing arrangement used in this relay family, which influences how the device engages in response to control signals within bias-driven applications. This type of relay typically serves in signal and control paths where a reliable, bias-informed switching element is required, offering a compact form factor and compatibility with vintage Fairchild hardware. For successful integration, refer to the supplier datasheet or catalog to confirm the coil characteristics, contact configuration, mounting style, and physical footprint for your design.
