Honeywell 112TW401-2 Toggle Switch Technical Guide
The Honeywell 112TW401-2 toggle switch is a sealed TW Series operator control device designed for professional switching applications where compact form, environmental resistance, and straightforward control logic are essential. This model is listed as a DPST panel mount toggle switch with an On-Off switch function, making it suitable for systems that need a simple maintained two-state control across two poles.
Technical Specifications of the Honeywell 112TW401-2 Toggle Switch
The Honeywell 112TW401-2 toggle switch features a double-pole single-throw circuit and is rated at 5 A for 125 V AC and 28 V DC operation. It uses a flatted actuator rather than the standard round style seen on some other TW variants, and the actuator length is approximately 17.27 mm. The switch is designed for panel mounting with a 12.40 mm circular cutout and a 15/32-32 threaded bushing.
Like other sealed TW Series products, the Honeywell 112TW401-2 operator control toggle switch uses an environment-sealed construction. This matters in technical environments where hardware may be exposed to splash, dust, vibration, or frequent operator handling. The operating temperature range of -65°C to 71°C gives it a strong profile for industrial and equipment-level use.
Why a DPST On-Off Toggle Switch Is Useful
The Honeywell 112TW401-2 DPST toggle switch is well suited for applications where two poles need to open and close together using one manual control point. That can be useful in equipment isolation, paired circuit switching, subsystem enable functions, and machine-level control logic where a simple maintained on-off action is the best fit. Because the function is straightforward, this model often appeals to engineers looking for reliability and mechanical durability rather than complex switching behavior.
Application Areas for the 112TW401-2
The Honeywell 112TW401-2 toggle switch can be used in industrial panels, instrumentation, mobile equipment, test systems, machinery interfaces, and retrofit projects that need a compact sealed switch with a flatted actuator. Common search interest includes phrases such as DPST panel mount toggle switch, sealed On-Off toggle switch, and Honeywell 112TW401-2 operator control switch. For more information about Honeywell, exploring the wider TW Series can help distinguish between flatted actuator and round actuator versions.
FAQ: Honeywell 112TW401-2 Toggle Switch
What type of switch is the Honeywell 112TW401-2?
The Honeywell 112TW401-2 is a DPST panel mount toggle switch with a maintained On-Off function. It is designed for professional equipment and control applications.
What does DPST mean on the Honeywell 112TW401-2?
DPST means double-pole single-throw. In practice, this allows two separate poles to switch together between on and off using one actuator.
Why does the 112TW401-2 use a flatted actuator?
A flatted actuator changes the lever profile and can support a different operator feel or panel design preference compared with a standard round actuator. It is also a useful identifier when matching replacement parts.
Is the Honeywell 112TW401-2 suitable for sealed equipment panels?
Yes. The switch is part of Honeywell’s sealed operator control family and is intended for applications where environmental protection helps improve service reliability.
What should engineers check before specifying the 112TW401-2?
They should confirm the required pole configuration, on-off function, electrical load, mounting dimensions, actuator style, and ambient operating conditions before finalizing the design.
