Midco International 627820 Switching Relay 24V 3A

The Midco International 627820 Switching Relay is an electrical control component that manages low-voltage signal switching. In HVAC systems it receives a 24V input and operates a contact rated at 3A to open or close electrical pathways for connected equipment. This relay coordinate control signals between thermostats, fans, and other system components, ensuring proper sequence of operation. It is applied in control panels where switching of low-current circuits is required to support system logic and equipment response. The unit converts control signals into mechanical contact action for stable electrical switching.
