Honeywell 112TW401-5 Toggle Switch Technical Overview
The Honeywell 112TW401-5 toggle switch is a sealed operator control component from the TW Series, developed for applications that require both maintained and momentary switching behavior in a compact panel-mount design. This model is listed as a DPDT toggle switch with an On-Off-Mom switch function, which makes it useful when one side should remain maintained, the center should be off, and the opposite side should activate only while the lever is held.
Technical Features of the Honeywell 112TW401-5 Toggle Switch
The Honeywell 112TW401-5 toggle switch uses a double-pole double-throw circuit and is rated at 5 A for 125 V AC and 28 V DC. It features a flatted actuator with an actuator length of approximately 17.27 mm. The switch is intended for panel mounting and uses a 12.40 mm circular panel cutout with a 15/32-32 bushing thread.
A major advantage of the Honeywell 112TW401-5 operator control toggle switch is its environment-sealed construction. That helps protect the switching mechanism in conditions where dust, splash, and vibration are part of the normal operating environment. The operating temperature range of -65°C to 71°C also supports deployment in demanding technical installations.
Why the On-Off-Mom Function Is Important
The Honeywell 112TW401-5 DPDT toggle switch is not just a basic selector. Its On-Off-Mom arrangement allows one maintained active position, a neutral off center, and one momentary position. This makes it useful in control panels, reset logic, directional systems, temporary override commands, and machine interfaces where one action should remain selected while another should occur only briefly.
Where the Honeywell 112TW401-5 Toggle Switch Is Used
The Honeywell 112TW401-5 toggle switch is relevant in industrial machinery, instrumentation, aerospace-adjacent systems, test equipment, service panels, and retrofit projects that need a sealed flatted-actuator toggle switch. Common keyword demand often centers on DPDT On-Off-Mom toggle switch, sealed panel mount toggle switch, and Honeywell 112TW401-5 operator control switch.

FAQ: Honeywell 112TW401-5 Toggle Switch
What type of switch is the 112TW401-5?
The Honeywell 112TW401-5 is a DPDT panel mount toggle switch with an On-Off-Mom function. It is designed for technical environments where durable manual switching is required.
What does On-Off-Mom mean on the 112TW401-5?
It means one position is maintained on, the center is off, and the opposite position is momentary. This gives designers a practical mix of stable state control and temporary command input.
Why is a flatted actuator relevant on the 112TW401-5?
The flatted actuator changes the lever profile and can matter for operator feel, panel layout, and replacement matching. In maintenance work, actuator style is often one of the most important identifiers.
Is the 112TW401-5 suitable for demanding environments?
Yes. Its sealed construction and wide operating temperature range make it a strong candidate for equipment that must operate reliably in industrial or exposed service conditions.
What should be checked before choosing the Honeywell 112TW401-5?
Engineers should confirm the DPDT requirement, the On-Off-Mom switching logic, actuator style, panel mounting dimensions, environmental exposure, and electrical load profile before specifying the part.
