Honeywell 13AT471-T2 Toggle Switch: AT Series and Military Reference Explained

The Honeywell 13AT471-T2 operator controls accessory is a Honeywell AT Series panel-mount toggle switch that appears in current listings as a DPDT model with a Mom-Off-Mom switching function, 5 A AC/DC rating, 115 V AC rating, 28 V DC rating, flatted actuator, 16.26 mm actuator length, solder turret termination, 12.40 mm circular panel cutout, and 15/32-32 bushing thread. DigiKey also lists the product as obsolete. In the Honeywell AT Series catalog, 13AT471-T2 is shown as a MIL-S-8805/26 version tied to military number M8805/26-006 in the tab-lever T2 configuration, which adds an important identification point for legacy aerospace, defense, and ruggedized equipment contexts.

What the Honeywell 13AT471-T2 is designed to do

Unlike a maintained selector switch, the Honeywell 13AT471-T2 toggle switch uses momentary action on both sides with an off center position. That makes it suitable for temporary control commands such as pulse input, controlled actuation, or spring-return operator functions. Because it is a DPDT configuration, it can manage two poles simultaneously while preserving a compact panel footprint. This is one reason engineers often search for terms like Honeywell 13AT471-T2 switch, Honeywell 13AT471-T2 operator controls accessory, or Honeywell DPDT momentary toggle switch when supporting older industrial or specialized control hardware.

Why the military reference matters

For older equipment, a military reference is often as useful as the commercial part number. Honeywell’s AT Series catalog maps 13AT471-T2 to M8805/26-006, which helps maintenance teams validate whether a given switch was originally selected for more demanding environments or specification-driven projects. That does not automatically define the entire application, but it does strengthen traceability in legacy documentation, defense support records, and long-life equipment programs where commercial and military references are used side by side.

Fit, lifecycle, and replacement logic

Because this model is listed as obsolete by a major distributor, replacement work depends on understanding the real essentials: momentary center-off function, DPDT circuit, panel-mount geometry, 15/32-32 bushing, and the 115 V AC / 28 V DC rating profile shown in current listings. Those elements matter more than cosmetic similarity. For that reason, the Honeywell 13AT471-T2 operator controls accessory remains a valuable reference code in service, retrofit, and documentation work even if the original stock is limited.

FAQ

What type of switch is the Honeywell 13AT471-T2?

It is listed as a DPDT panel-mount Honeywell AT Series toggle switch with a momentary-off-momentary function.

What ratings are associated with the Honeywell 13AT471-T2?

Current product data shows 5 A AC/DC, 115 V AC, and 28 V DC. These values are especially useful when identifying legacy hardware.

Is the Honeywell 13AT471-T2 obsolete?

Yes. One major distributor explicitly marks it as obsolete and no longer manufactured, so accurate cross-reference work is often required.

Does this model have a military reference number?

Yes. Honeywell’s AT Series catalog maps 13AT471-T2 to military number M8805/26-006, which is highly useful in legacy documentation and maintenance traceability.
