Honeywell 4074EKV Auxiliary Switch

The Honeywell 4074EKV is a heavy-duty auxiliary switch kit designed for field installation on M6415, M7215, M7415, and M8415 series damper actuators. This 24Vac SPDT snap-acting switch allows technicians to synchronize auxiliary equipment, such as fans or indicators, directly with the actuator's shaft position. As a direct equivalent to the 4074EKV/U, it features an adjustable cam that provides precise control over the make/break points across the full 90-degree actuator stroke. Rated for 40VA pilot duty and capable of handling up to 7.2A full load at 120Vac, the Honeywell auxiliary switch ensures reliable switching in demanding HVAC economizer systems. The kit includes the mounting plate, switch cam, and an insulating boot to maintain electrical integrity in tight terminal enclosures. Engineered for durability, it operates effectively in ambient temperatures ranging from -25?F to +125?F, making it a standard for commercial damper motor control upgrades and repairs.

• Universal Compatibility: Seamlessly integrates with M6415, M7215, M7415, M8405, and M8415 actuators.
• Precision Timing: Adjustable circular cam allows for custom make/break settings anywhere in the motor's rotation.
• Complete Hardware Kit: Includes mounting plate, insulating boot, and necessary 4-40 screws for a flush, secure fit.
• High Amperage Rating: Reliable SPDT contacts support 120/240 Vac loads for various auxiliary peripheral devices.
• Flexible Application: Suitable for controlling fans, relays, or position-indication lights in economizer circuits.

Is the Honeywell 4074EKV the same as the 4074EKV/U?
Yes, the 4074EKV is technically identical to the 4074EKV/U; the "U" suffix typically denotes a universally packaged version for retail or wholesale distribution.

Can I adjust the switch to trip at a specific damper position?
Exactly. The included circular switch cam is fully adjustable, allowing you to set the auxiliary contact to engage at any specific point during the actuator's 90-degree stroke.

Does this kit include the mounting hardware?
Yes, the kit is provided with the mounting plate, snap-acting switch, insulating boot, cam, and the specialized screws required to mount the switch assembly flush against the actuator side panel.
