Honeywell 112TW8-10A Toggle Switch Technical Guide
The Honeywell 112TW8-10A toggle switch is a specialized control component from the TW Series, designed for applications that require a compact sealed switch with multi-position logic. Unlike more common two-position toggle devices, this model features an SP3T circuit and an On-On-On switch function. That makes it relevant for systems where one input must select between three active paths rather than simply switching between on and off.
Technical Features of the Honeywell 112TW8-10A
The Honeywell 112TW8-10A SP3T toggle switch is rated for 100 mA at 125 V AC and 28 V DC. It is built for panel mounting and uses an IWTS termination style. One of the most notable design elements is the locking lever actuator, which helps reduce the likelihood of accidental switching in sensitive control applications. The switch is also environment sealed, making it better suited for demanding operating conditions than an unsealed alternative.
Additional mechanical details include a 12.40 mm circular panel cutout, 15/32-32 bushing thread, and operation over a wide temperature range of -65°C to 71°C. The product listing also notes that a jumper is needed to achieve triple throw, an important design detail for engineers working on wiring and circuit layout.
Application Relevance of the Honeywell 112TW8-10A Toggle Switch
The Honeywell 112TW8-10A operator control switch is often considered for aerospace, defense, instrumentation, and high-reliability panel assemblies where a stable three-position selection interface is needed. A locking lever can be especially useful in these environments because it helps prevent unintended actuation during vibration, movement, or routine operator contact.
For teams researching a Honeywell 112TW8-10A toggle switch, the value lies not just in its electrical rating but in the overall switching behavior. Three-position logic can simplify panel design by allowing one compact switch to handle mode selection, signal routing, or staged control functions that would otherwise require multiple components.
Selection and Integration Notes
When specifying a three-position toggle switch, it is essential to verify circuit logic, actuator behavior, and installation details. The Honeywell 112TW8-10A toggle switch supports that process with a sealed body, clearly defined mounting dimensions, and a locking actuator style that aligns with professional control environments.

FAQ About Honeywell 112TW8-10A
What type of switch is the Honeywell 112TW8-10A?
It is an SP3T panel mount toggle switch with an On-On-On function, designed for three-position switching in compact control systems.
What is special about the Honeywell 112TW8-10A locking lever?
The locking lever helps reduce accidental actuation. That makes the switch especially useful in technical environments where unintended switching could interrupt a process or create operator confusion.
What is the current rating of the Honeywell 112TW8-10A toggle switch?
This model is rated for 100 mA at 125 V AC and 28 V DC. It is therefore more aligned with signal and control functions than higher-current power switching tasks.
Is the 112TW8-10A sealed?
Yes. The Honeywell 112TW8-10A toggle switch is listed as environment sealed, which supports use in more demanding installation conditions.
Why is the jumper note important on the Honeywell 112TW8-10A?
The product attributes indicate that a jumper is needed to achieve triple throw. This matters because proper wiring is essential to get the intended three-position switching behavior.
Where is the 112TW8-10A commonly used?
It is commonly associated with aerospace panels, instrumentation controls, specialist machinery, and other applications where a sealed, compact, three-position toggle switch with a locking action is valuable.
