Carrier Auxiliary Contact Switch for HVAC Contactors

The Carrier Auxiliary Contact Switch (also called a contact auxiliary switch or auxiliary contact block) is an OEM electrical component for Carrier HVAC systems. It works with an HVAC contactor to give you extra control and monitoring of the electrical circuit.

Key Features:

• Genuine Carrier OEM part: Made for use with Carrier HVAC equipment.
• Auxiliary switching: Opens or closes contacts in response to changes in the primary contactor circuit.
• Control and feedback: Helps monitor contactor status and supports interlocking of secondary components in the control circuit.
• Field replacement: Replaces a worn or failed auxiliary contact so the system keeps operating reliably.

Choose the part number that matches your equipment. Both options are the same Carrier auxiliary contact switch product line.
