Honeywell 104TL2-3 Operator Controls

The Honeywell 104TL2-3 operator controls model is one of the more straightforward and useful configurations in the Honeywell TL Series. According to Honeywell’s order guide, this part is a 4PST two-position switch with circuit continuity on both active positions rather than an OFF position. For many panel designs, that makes it a practical choice where grouped circuits need to move between two defined states.

Why Honeywell 104TL2-3 Stands Out

The Honeywell 104TL2-3 operator controls switch is part of the sealed TL platform that Honeywell qualifies to MIL-DTL-3950. This family is built for harsh-duty use and includes bonded seals that help prevent the ingress of dust and liquids. Honeywell also positions the series for aerospace, military support equipment, construction machinery, and other environments where reliability is essential.

Technical Characteristics

In the four-pole two-position order guide, Honeywell identifies 104TL2-3 as a model where the four poles switch from one closed set of circuits to another closed set of circuits. In simple terms, it is a 4PST on-on style arrangement for operators who need a positive transfer between two states. The TL family also supports operating temperatures from -65°C to 71°C, a 15/32 in mounting bushing, and terminations including IWTS. Honeywell further notes approvals such as UL, CSA, CE, and UKCA at the family level.

Best-Fit Applications

The Honeywell 104TL2-3 operator controls part fits applications where multiple circuits must change state together, especially in rugged consoles or equipment cabins. It is a useful reference for engineers in off-road equipment, defense support systems, and industrial machinery retrofits.

What gives the part long-term value is not only its switch action, but also the combination of sealing, environmental range, and mechanical consistency that comes with the TL Series design language.

For more information about Honeywell, reviewing related TL variants can help identify whether a maintained two-position or three-position format is the better fit.

FAQ

What switch action does the Honeywell 104TL2-3 use?

Honeywell lists it in the four-pole two-position order guide as a 4PST configuration that changes between two active circuit states.

Is the Honeywell 104TL2-3 sealed?

Yes. It belongs to the sealed TL Series and is designed for rugged-duty environments.

What industries typically use this part?

It is relevant in aerospace support, heavy equipment, industrial panels, and other demanding installations.

What makes it different from an OFF-ON toggle?

Instead of switching between OFF and ON, this configuration transfers between two active circuit conditions.

Does the TL Series support low and high temperature operation?

Yes. Honeywell specifies a family operating range from -65°C to 71°C.
