Honeywell 112TW1-8F Locking Lever Toggle Switch Guide
The Honeywell 112TW1-8F toggle switch is a TW Series operator control device designed for applications where compact construction, environmental sealing, and controlled manual actuation are all required. This model is configured as a DPDT toggle switch with an On-Mom switch function and a locking lever actuator. That combination makes it especially relevant when a system needs both a maintained switching state and a more deliberate mechanical action to prevent accidental operation.
Technical Overview of the Honeywell 112TW1-8F Toggle Switch
The Honeywell 112TW1-8F locking lever toggle switch is a panel mount DPDT switch with a 5 A electrical rating, typically shown at 125 V AC and 28 V DC or 30 V DC depending on distributor formatting. It uses a locking lever rather than a standard round actuator, and the actuator length is approximately 29.46 mm. It is mounted in a 12.40 mm circular panel cutout and uses a 15/32-32 threaded bushing, which supports dimensional consistency across TW Series installations.
The product is also associated with an environment-sealed housing, allowing it to fit demanding use cases involving dust, splash, and vibration. The Honeywell 112TW1-8F toggle switch is specified for an operating temperature range of -65°C to 71°C, which is one reason it remains relevant in industrial and transport-related control applications.
Why the F Locking Configuration Is Important
One of the most important features of the Honeywell 112TW1-8F DPDT toggle switch is the locking behavior connected to the F suffix. Distributor and catalog references commonly associate this version with a locked extreme position arrangement. In operational terms, that means the switch is designed to add a deliberate action requirement when moving through a critical position. In environments where accidental switching can disrupt equipment behavior or operator workflow, that added control can be highly valuable.
Where the Honeywell 112TW1-8F Toggle Switch Is Used
The Honeywell 112TW1-8F operator controls switch is often evaluated for industrial control panels, rugged instrumentation, aerospace-related support systems, specialty machinery, mobile equipment, and retrofit projects that need a sealed locking toggle format. Search traffic is often built around terms such as locking lever toggle switch, Honeywell 112TW1-8F toggle switch, sealed DPDT switch, and panel mount locking toggle switch.

FAQ: Honeywell 112TW1-8F Toggle Switch
What type of switch is the Honeywell 112TW1-8F?
The Honeywell 112TW1-8F is a DPDT panel mount toggle switch with a locking lever actuator. It belongs to the Honeywell TW Series and is intended for professional control applications.
What does the On-Mom function mean on the Honeywell 112TW1-8F?
It means one switch position is maintained while the opposite position is momentary. This allows the switch to support both a stable control state and a temporary command input.
Why would someone choose a locking lever version instead of a standard lever?
A locking lever version adds a more controlled actuation profile. This can help reduce accidental switching and support more intentional operator input in critical equipment.
Is the 112TW1-8F suitable for sealed control panels?
Yes. Its environment-sealed construction is one of the key reasons it is used in sealed or semi-exposed panel installations where contamination or moisture can affect long-term reliability.
What should engineers verify before specifying the 112TW1-8F?
They should verify the required switch logic, locking behavior, actuator clearance, mounting dimensions, electrical rating, and environmental conditions. Those factors determine whether the switch is the right fit for the target application.
