Honeywell 112TW8-7 Toggle Switch Guide
The Honeywell 112TW8-7 toggle switch is a sealed panel-mount control component built for applications that require a dependable momentary action with a defined neutral center state. As part of the Honeywell TW Series, this model is configured as a DPDT toggle switch with a Mom-Off-Mom function. That makes it especially relevant where both active positions should return automatically to off after release.
Technical Overview of the Honeywell 112TW8-7
The Honeywell 112TW8-7 DPDT toggle switch is rated for 100 mA at 125 VAC and 28 VDC. It is designed for panel mounting and uses an IWTS termination style. In product listings, this model is associated with a standard round lever, giving it a familiar mechanical feel while still fitting within a rugged sealed switch family.
Mechanical details also matter here. The Honeywell 112TW8-7 toggle switch uses a 12.40 mm circular panel cutout and a 15/32-32 threaded bushing. It is listed as environment sealed and supports operation from -65°C to 71°C. Those characteristics make it useful in technical installations where environmental exposure and reliable repeat operation are part of the specification process.
What Makes the Honeywell 112TW8-7 Useful?
For engineers and maintenance professionals, the value of the Honeywell 112TW8-7 operator control switch lies in its switching logic. A momentary-off-momentary profile is often selected for directional commands, temporary activation, test routines, jog control, and applications where the switch should never remain engaged by mistake. That can improve both operator control and process safety.
Because the current rating is relatively low, the Honeywell 112TW8-7 toggle switch is more aligned with signal-level and control-level duties than with heavy load switching. In the right design context, that is exactly what makes it valuable. It supports precise operator input without adding unnecessary bulk.
Integration Considerations
When selecting a replacement or specifying a new component, it is important to verify more than the product code. Circuit type, lever style, switching action, mounting dimensions, and sealing should all be checked together. The Honeywell 112TW8-7 toggle switch is a strong fit where compact sealed performance and repeatable momentary action are priorities.

FAQ About Honeywell 112TW8-7
What type of switch is the Honeywell 112TW8-7?
It is a DPDT panel mount toggle switch with a Mom-Off-Mom function. Both active positions are momentary and return to the center off state when released.
What is the electrical rating of the Honeywell 112TW8-7 toggle switch?
The switch is commonly listed at 100 mA at 125 VAC and 28 VDC, which makes it suitable for control and signal applications.
Does the 112TW8-7 have a sealed construction?
Yes. The Honeywell 112TW8-7 toggle switch is listed as environment sealed, a key characteristic for applications exposed to dust or challenging operating conditions.
What actuator style is used on the 112TW8-7?
Listings commonly associate this model with a standard round lever, which influences both the feel of operation and compatibility with existing panel designs.
Where is the 112TW8-7 commonly applied?
It is suitable for technical control panels, specialist equipment, instrumentation interfaces, and other systems where temporary directional or command inputs are preferred over maintained switching.
Why is momentary action important in the 112TW8-7?
Momentary action helps ensure the switch returns to neutral automatically. This can reduce the risk of an unintended sustained command and support more deliberate operator interaction.
