Honeywell 112TW26-7 Toggle Switch Technical Guide
The Honeywell 112TW26-7 toggle switch is a compact sealed operator control component designed for applications that require dependable manual actuation in demanding environments. As part of the Honeywell TW Series, this model is built as a DPDT toggle switch with a Mom-Off-Mom switch function. That means both active end positions are momentary, while the center remains off. In practical terms, this makes the switch a strong fit for control systems where commands should only remain active while the lever is intentionally held.
Technical Specifications of the Honeywell 112TW26-7 Toggle Switch
The Honeywell 112TW26-7 toggle switch uses a double-pole double-throw circuit and is commonly listed with a 2 A current rating at 115 V AC. It is designed for panel mounting and features a standard round actuator with an actuator length of approximately 17.27 mm. The switch fits a 12.40 mm circular panel cutout and uses a 15/32-32 bushing thread, which helps maintain compatibility in TW Series installations.
Another important feature of the Honeywell 112TW26-7 operator control toggle switch is its environment-sealed construction. In industrial, transport, and instrumentation environments, this matters because switches are often exposed to dust, splash, handling stress, and vibration. The operating temperature range of -65°C to 71°C also supports use in challenging ambient conditions.
Why the Mom-Off-Mom Function Matters
The Honeywell 112TW26-7 DPDT toggle switch is especially relevant in applications where a maintained state could create operational risk or reduce control precision. Because both active positions are momentary, the operator must keep holding the lever for the command to stay active. This is useful in directional controls, jog functions, reset logic, and temporary signal routing where intentional control is more important than latching behavior.
Application Areas for the Honeywell 112TW26-7 Toggle Switch
The Honeywell 112TW26-7 toggle switch can be used in industrial machinery, specialist equipment, instrumentation panels, mobile systems, and rugged control interfaces where a sealed compact switch is preferred. Search interest around this model is often linked to terms such as DPDT momentary toggle switch, sealed panel mount toggle switch, and Honeywell 112TW26-7 operator control switch.

FAQ: Honeywell 112TW26-7 Toggle Switch
What type of switch is the Honeywell 112TW26-7?
The Honeywell 112TW26-7 is a DPDT panel mount toggle switch with a Mom-Off-Mom switching function. It is intended for professional applications where both durability and controlled actuation are important.
What does Mom-Off-Mom mean?
Mom-Off-Mom means both active end positions are momentary and the switch returns to the center off position when released. This is useful when commands should only remain active while the user is deliberately holding the lever.
Is the 112TW26-7 suitable for harsh environments?
Yes. The switch is part of a sealed operator control family, which supports use in environments where dust, moisture, and vibration may affect standard switching hardware.
Why do engineers choose a DPDT toggle switch like the 112TW26-7?
A DPDT switch can control two circuits at the same time. That makes it useful for paired signal changes, reversing functions, directional controls, and coordinated switching tasks in technical equipment.
What should be checked before specifying the Honeywell 112TW26-7?
The main points to confirm are current and voltage requirements, switch function, actuator style, mounting dimensions, and whether a momentary-both-sides action is appropriate for the target application.
