TOOWEI has upgraded the full T500 and T800 toggle switch series from IP67 to IP68 front-panel protection. The updated designs are tested at a water depth of 1 meter for 1 hour, while electrical ratings, switching functions, pole configurations, and terminal options remain unchanged.
TOOWEI has completed a sealing-performance upgrade across the full T500 and T800 toggle switch series.
The previous IP67 versions have now been replaced by updated IP68 configurations, providing improved front-panel protection for equipment exposed to water, dust, moisture, and demanding operating environments.
The upgrade applies to all models within both series.
IP68 Front-Panel Protection
The upgraded T500 and T800 toggle switches provide IP68 protection for the switch components located above the mounting panel when correctly installed.
The protection level has been tested under the following conditions:
• Water depth: 1 meter
• Test duration: 1 hour
• Protection area: Front-panel components of the switch
This means the lever, mounting bushing, sealing interface, and other exposed components above the panel are designed to resist water and dust under the specified test conditions.
The IP68 rating should be understood as front-panel protection rather than a general claim that every terminal configuration is completely waterproof.
Fully Sealed Potted-Wire Versions
For applications where the rear connection area may also be exposed to water or contaminants, T500 and T800 potted-wire versions provide a fully sealed structure.
In these configurations, the rear wire connection area is sealed rather than left with exposed terminals.
This design is suitable for applications where protection is required not only above the mounting panel, but also around the back of the switch and wire exit.
Potted-wire versions may be particularly useful for:
• Outdoor equipment
• Construction machinery
• Agricultural machinery
• Special vehicles
• Marine equipment
• Exposed control panels
• Equipment operating in wet or dusty environments
The wiring harness, connector, and cable termination used outside the switch should also be selected according to the environmental requirements of the complete system.
Electrical Performance Remains Unchanged
The IP68 upgrade focuses on environmental sealing performance.
The established electrical ratings of both product series remain unchanged:
• 15A 250VAC
• 20A 125VAC
Customers can continue using the existing electrical specifications when evaluating the upgraded versions.
The upgrade does not require changes to the basic electrical load selection, provided that the original product configuration remains suitable for the application.
Existing Configurations Remain Available
The original configuration range of the T500 and T800 series remains unchanged.
Available options continue to include different:
• Pole configurations
• Switching functions
• Terminal styles
• Momentary and maintained actions
• Standard and wire-lead versions
Depending on the selected model, circuit options may include:
• SPST
• SPDT
• DPST
• DPDT
Available switching functions may include:
• ON-OFF
• ON-ON
• ON-OFF-ON
• Momentary functions
• Mixed maintained and momentary functions
This allows current customers to move to the upgraded IP68 series without changing the basic switching logic of their equipment.
No Change to Panel and Electrical Selection Logic
Because the electrical parameters and product configuration options remain unchanged, equipment manufacturers do not need to redesign the complete control circuit solely because of this protection upgrade.
However, buyers should still confirm:
• Exact model
• Circuit function
• Pole configuration
• Terminal type
• Panel cutout
• Rear clearance
• Wire requirements
• Environmental exposure
For projects previously using the IP67 versions, the updated IP68 models should be reviewed against the existing drawing and approved sample before volume production.
Why the Upgrade Matters
Switches installed on exposed equipment panels may encounter:
• Rain
• Water spray
• Dust
• Mud
• Humidity
• Outdoor storage
• Cleaning water
• Temperature changes
Improved sealing performance helps equipment manufacturers select the T500 and T800 series for a wider range of applications where front-panel environmental protection is required.
The upgrade is particularly relevant for OEM manufacturers that need stable switch operation in outdoor, mobile, or moisture-prone equipment.
T500 Series Applications
The T500 series is suitable for applications requiring a high-current toggle switch with multiple circuit and function options.
Typical applications may include:
• Equipment control panels
• Construction machinery
• Agricultural machinery
• Special vehicles
• Marine control systems
• Outdoor equipment
• Auxiliary power controls
• Lighting and mode selection
The series supports standard terminal configurations as well as sealed potted-wire versions for applications requiring additional rear protection.
T800 Series Applications
The T800 series combines multiple switch configurations with a sealed structure designed for equipment controls operating in demanding environments.
It may be used in:
• Vehicle control systems
• Outdoor machinery
• Agricultural equipment
• Marine panels
• Equipment consoles
• Power control systems
• Mobile equipment
• Exposed operator controls
Potted-wire configurations provide an additional option for customers requiring a fully sealed rear connection structure.
Previous IP67 Versions Discontinued
The earlier IP67 versions of the T500 and T800 series are no longer supplied.
All models in both series have been upgraded to IP68 front-panel protection.
This change simplifies product selection and ensures that new orders receive the updated sealing performance without requiring a separate IP68 option.
Customers with existing approved products should confirm the latest drawing, specification, and sample before placing repeat production orders.
Accurate Protection Description
For technical documents and equipment specifications, TOOWEI recommends using precise descriptions.
For standard terminal versions:
IP68 front-panel protection, tested at 1 meter water depth for 1 hour.
For potted-wire versions:
IP68 front-panel protection with a fully sealed potted-wire structure.
This wording clearly distinguishes front-panel protection from rear sealing and avoids the broad use of unsupported waterproof claims.
What Remains the Same
The following product characteristics remain unchanged after the upgrade:
• Rated current and voltage
• Pole options
• Switching functions
• Terminal options
• Product selection logic
• Main installation structure
• Application range
The key change is the improvement from IP67 to IP68 front-panel protection.
Support for OEM Applications
TOOWEI can support OEM equipment manufacturers with product selection and configuration confirmation based on:
• Required circuit function
• Electrical rating
• Pole configuration
• Panel dimensions
• Terminal type
• Wire length
• Wire gauge
• Connector requirements
• Environmental exposure
Customized wire leads and connectors may be available depending on the selected model and order requirements.
Conclusion
The T500 and T800 toggle switch series have been fully upgraded from IP67 to IP68 front-panel protection.
The updated products are tested at a water depth of 1 meter for 1 hour, while maintaining the original 15A 250VAC / 20A 125VAC electrical ratings and existing configuration options.
For applications requiring additional protection behind the mounting panel, potted-wire versions provide a fully sealed rear connection structure.
This upgrade strengthens the suitability of the T500 and T800 series for outdoor equipment, machinery, vehicles, marine systems, and other demanding control applications.
