Lennox 67K19 Relay SPST 120V

The Lennox 67K19 is a Single Pole Single Throw (SPST) relay, a switch specifically designed for HVAC equipment like furnaces and air conditioners. It controls the flow of electrical current based on a received signal. In simpler terms, when activated by a low-voltage control circuit, the relay switches on or off a higher-voltage circuit. This allows the relay to control various components within the HVAC system, such as motors, solenoids, or lights. This particular Lennox relay is built to handle a 120V power supply and functions at both 50 and 60 Hertz (Hz) frequencies. Its compact size, measuring 2.2 inches long, 2.53 inches wide, and 1.39 inches high, makes it suitable for tight spaces within HVAC units. Furthermore, it weighs a mere 0.21 pounds. By offering reliable switching functionality, the Lennox 67K19 relay plays a critical role in regulating various HVAC components and ensuring the system's overall operation.
