2-Wire Fan Delay Switch

The Russell 103079-09 2-Wire Fan Delay Switch is engineered to manage the operational timing of motors by introducing a delay in either the start-up or shut-down sequence. This component is crucial for equipment that requires precise control over fan operation, such as cooling units and other temperature-regulating systems. Featuring 15-inch leads, this switch facilitates the transfer of electrical signals between the equipment's control system and the fan assembly. The switch operates within a specific temperature range, closing at 35°F (2°C) and opening at 45°F (7°C), making it suitable for applications where temperature fluctuations dictate fan activity. Installation involves disconnecting power, identifying the existing switch, detaching the two-wire connections, verifying the new switch matches the old one, and securely attaching the leads. Proper polarity is essential for correct function. The switch should be positioned back in its original location to prevent undue stress on the leads. After reapplication of power, the fan's response to temperature changes should be observed to confirm proper operation.
