Honeywell 220736B Internal Auxiliary Switch

The Honeywell 220736B Internal Auxiliary Switch kit is an essential field-addable component designed for Honeywell Modutrol IV Motors. This high-precision kit features two SPDT Micro Switch V3 switches, allowing for the control of auxiliary equipment based on the motor shaft's position. Whether you are managing indicator lights, secondary dampers, or stage-dependent HVAC sequencing, the 220736B provides the reliability required for industrial and commercial actuator controls. The switches are actuated by adjustable cams factory-mounted on the motor shaft, enabling a technician to set precise actuation points at any angle within the motor's stroke. With a switching differential selectable at approximately 1° or 10°, this kit offers the granular control needed for sensitive HVACR systems. Engineered for efficiency, it features color-coded leadwires and a dedicated mounting bracket for a fast, secure internal installation that maintains the low-profile footprint of the Modutrol IV series.

• Dual-Circuit Control: Includes two Single Pole Double Throw (SPDT) switches to manage multiple auxiliary functions from a single motor.
• Field-Adjustable Accuracy: Flexible cam settings allow for actuation at any point in the rotation, providing superior actuator motor positioning.
• Rugged Temperature Rating: Built to withstand demanding mechanical rooms with an ambient temperature range of 0°F to 131°F.
• High Electrical Capacity: Rated for 120/240 Vac with 7.2A AFL at 120V, ensuring compatibility with standard control circuits.
• Standardized Fit: Specifically compatible with TRADELINE Modutrol IV Motors, ensuring a drop-in internal fit with pre-installed cam assemblies.

Which motors are compatible with the 220736B?
This kit is designed specifically for Honeywell TRADELINE Modutrol IV Motors. It integrates directly with the factory-installed cam assemblies found in these series to provide additional auxiliary switch contacts.

How do you adjust the switching differential?
The differential of 1° or 10° is determined by the specific cam lobe used. The fast-rise portion of the cam provides a tighter 1° differential, while the slow-rise portion is used for a 10° differential to prevent rapid cycling of connected equipment.

Does this switch kit include the required mounting hardware?
Yes, the Honeywell 220736B comes factory-installed on a specialized mounting bracket with two screws for internal attachment to the motor housing.
