Honeywell 112TW401-7 Toggle Switch Overview

The Honeywell 112TW401-7 toggle switch is a compact sealed operator control designed for demanding panel-mounted applications. Built within Honeywell’s well-known TW Series, this model combines a DPDT circuit with a Mom-Off-Mom switch function, making it suitable for control logic that requires two momentary positions with a center-off state. In practical terms, that gives engineers and maintenance teams a reliable option for equipment that must return to neutral when released.

Key Technical Characteristics of the Honeywell 112TW401-7 Toggle Switch

The Honeywell 112TW401-7 DPDT toggle switch is rated for 5A at 125 V AC and 28 V DC. It uses a panel mount configuration, a flatted actuator, and an IWTS termination style. The actuator length is 17.27 mm, while the recommended panel cutout is 12.40 mm with a 15/32-32 bushing thread. One of its most relevant advantages is its environment-sealed construction, which supports use in challenging industrial and mobile equipment environments.

Where the Honeywell 112TW401-7 Fits Best

Because this Honeywell 112TW401-7 operator control switch uses a momentary-off-momentary action, it is often discussed in relation to aerospace controls, industrial panels, specialty vehicles, and rugged operator interfaces. The center-off design is useful when a command should only remain active while the lever is being held. That reduces the chance of a persistent unintended state and supports more deliberate operator input.

Another reason the Honeywell 112TW401-7 toggle switch is frequently selected for technical projects is its broad operating temperature range of -65°C to 71°C. This makes it relevant for low-temperature and variable-environment installations where ordinary commercial switches may not be the right fit.

Installation and Design Considerations

When evaluating a sealed toggle switch, engineers usually look beyond the current rating alone. Mounting geometry, actuator style, and sealing all matter. The Honeywell 112TW401-7 toggle switch offers a straightforward panel-mount design that supports structured control layouts. Its compact format can help where space is limited, while the sealed body is beneficial where dust, splash exposure, or environmental contaminants are a concern.

FAQ About Honeywell 112TW401-7

What type of switch is the Honeywell 112TW401-7?

It is a DPDT panel mount toggle switch with a Mom-Off-Mom switching function. That means both active positions are momentary and the lever returns to the center off position when released.

What is the electrical rating of the Honeywell 112TW401-7 toggle switch?

This model is rated for 5A at 125 V AC and 28 V DC. These values make it relevant for control circuits where dependable switching performance matters more than consumer-grade convenience.

Is the Honeywell 112TW401-7 sealed?

Yes. A major feature of the Honeywell 112TW401-7 toggle switch is its environment-sealed construction. This is useful in harsh environments where moisture, dust, or contamination may affect switch reliability.

What kind of mounting does the Honeywell 112TW401-7 use?

It is designed for panel mounting. The panel cutout is 12.40 mm in diameter, and the bushing thread is 15/32-32, which are important details for enclosure and panel planning.

Why would someone choose a Mom-Off-Mom Honeywell toggle switch?

A Mom-Off-Mom design is valuable when a system should only react while the operator is actively holding the lever. This makes it useful for temporary directional control, testing routines, reset behavior, and operator acknowledgment functions.

What makes the 112TW401-7 different from a basic toggle switch?

The combination of a sealed body, industrial panel mounting, DPDT circuitry, rugged temperature range, and controlled momentary action puts it in a much more specialized class than a standard light-duty toggle switch.
