Honeywell 13AT402-T2 Toggle Switch: Specifications, Function, and Use Cases
The Honeywell 13AT402-T2 operator controls accessory belongs to the Honeywell AT Series and is widely referenced as a Honeywell 13AT402-T2 toggle switch for industrial panels. Current product listings identify it as a DPDT panel-mount switch with an On-Off-On switching function, 5 A AC/DC rating, 250 V AC rating, 30 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. Honeywell’s AT Series order guide places 13AT402-T2 in the 3-position tab-lever configuration, confirming it as a maintained 3-position design rather than a momentary-only device.
Why the Honeywell 13AT402-T2 matters in control design
A maintained On-Off-On DPDT switch gives designers a straightforward way to provide stable position selection. That is often relevant in systems where an operator needs to choose between two active states with a neutral center position. In real-world control panels, that can mean mode selection, directional control logic, or routing two independent signal paths through one switch body. Because the Honeywell 13AT402-T2 operator controls accessory uses a familiar AT Series footprint, it is often searched as a Honeywell panel switch, Honeywell AT Series toggle switch, or Honeywell DPDT operator control.
Mechanical and installation characteristics
This variant is designed for panel mounting and uses solder turret terminals, which are helpful in builds where secure point-to-point wiring is preferred. The dimensional references are equally important: the 15/32-32 bushing and 12.40 mm circular cutout simplify identification during service work, especially in older machine panels where the original bill of materials may no longer be available. Even though current listings mark the product as obsolete, those mechanical details remain highly valuable for maintenance planning and cross-reference analysis.
Where this switch fits best
The Honeywell 13AT402-T2 toggle switch is best understood as a rugged, application-focused control component rather than a general-purpose consumer part. It suits industrial equipment, instrumentation interfaces, test stations, control cabinets, and retrofit assemblies that depend on tactile manual input. Engineers and buyers often land on this code when searching for a Honeywell 13AT402-T2 switch replacement, Honeywell 13AT402-T2 operator controls accessory, or Honeywell On-Off-On toggle switch with panel-mount construction.
FAQ
Is the Honeywell 13AT402-T2 a maintained 3-position switch?
Yes. The model is listed as On-Off-On, which indicates maintained positions on both sides with an off position in the center. Honeywell’s AT Series order guide also places it in the maintained 3-position tab-lever group.
What circuit format does the Honeywell 13AT402-T2 use?
It uses a DPDT circuit. That makes it suitable for switching two poles at once, which is useful in equipment that needs synchronized control paths.
What are the electrical ratings?
Current distributor data shows 5 A AC/DC, 250 V AC, and 30 V DC. Those figures are useful for identification, but engineers should still validate load type, inrush behavior, and environmental conditions before specifying a replacement.
Is this model still active?
One major distributor lists the 13AT402-T2 as obsolete and no longer manufactured. That makes precise dimensional and function matching especially important when sourcing an equivalent or replacing installed hardware.
