TOOWEI has introduced the A600 Series 12mm push button switch for equipment panels, remote controls, control grips, motorcycles, construction machinery, and power equipment. The series offers momentary and maintained functions, illuminated and non-illuminated versions, multiple button colors, IP67 front-panel sealing, and fully sealed wire-lead configurations.
TOOWEI has expanded its panel switch range with the introduction of the A600 Series 12mm push button switch.
The A600 Series was developed to provide equipment manufacturers with a compact and configurable control solution for applications requiring different operating actions, button colors, illumination options, and connection methods.
With a glossy nylon actuator, momentary and maintained functions, illuminated and non-illuminated configurations, and sealed wire-lead options, the A600 Series can be adapted to a wide range of equipment interfaces.
The new series is now available for sample evaluation and volume production.
Developed for Flexible Equipment Control Requirements
Equipment manufacturers rarely select a push button based on only one parameter.
The switch must fit the available panel space, match the required control logic, remain clear to the operator, connect efficiently to the wiring harness, and withstand the expected operating environment.
The A600 Series brings these requirements together in a compact 12mm panel-mount design.
Customers can select different:
• Operating actions
• Button shapes
• Button colors
• Illumination options
• LED colors
• Terminal configurations
• Wire-lead versions
• Contact materials
• Customized LED voltages
This flexibility allows the same product family to support multiple control functions across one equipment platform.
Compact 12mm Panel Mounting
The A600 Series is designed for a 12mm panel-mount installation.
Its compact size makes it suitable for:
• Dense control panels
• Handheld control units
• Remote-control boxes
• Control grips
• Operator consoles
• Motorcycle controls
• Equipment dashboards
• Power equipment
• Compact electrical assemblies
The 12mm format helps equipment designers add control functions without requiring a large panel area.
Before approving a model, customers should confirm the exact mounting drawing, thread dimensions, panel thickness, rear body clearance, and wiring space.
Momentary and Maintained Functions
The A600 Series is available with both momentary and maintained operating actions.
Momentary Action
A momentary push button changes the circuit state while the button is being operated and returns when released.
It can be used for functions such as:
• Start
• Reset
• Horn
• Test
• Jog control
• Temporary activation
• Controller input
• Remote command
Maintained Action
A maintained or latching push button remains in the selected state after operation.
It may be used for:
• Power control
• Lighting
• Equipment enable
• Mode selection
• Continuous auxiliary functions
• Manual control settings
The required action should be selected according to the complete equipment control logic.
The terms “momentary,” “latching,” and “maintained” describe the mechanical action. The exact electrical contact function should still be confirmed through the product drawing and wiring diagram.
Illuminated and Non-Illuminated Versions
The A600 Series is available in both illuminated and non-illuminated configurations.
Non-Illuminated Version
The non-illuminated version uses two terminals and provides a simple switching structure.
It is suitable when:
• A separate indicator light is already used
• No visual status feedback is required
• Simple wiring is preferred
• Panel cost needs to be controlled
• The function is identified by button color or panel labeling
Illuminated Version
The illuminated version uses four terminals, including separate connections for the switch contacts and LED circuit.
This allows the light and switching function to be controlled independently.
Illumination may be used to show:
• Power availability
• Active function
• Equipment status
• Mode selection
• System readiness
• Operator confirmation
The LED can be connected to follow the button state or controlled independently by the equipment circuit.
For many systems, using the LED to show the actual equipment status is more informative than showing only the physical switch position.
Center-Spot Illumination
The illuminated A600 version uses center-spot illumination.
Available LED colors include:
• Red
• Green
• Blue
• Yellow
• White
The standard LED voltage is 2.4V.
Other LED voltages can be customized by adding an appropriate resistor or adapting the LED circuit according to the customer’s power supply requirements.
Before ordering, customers should confirm:
• Supply voltage
• AC or DC supply
• LED polarity
• Required brightness
• Continuous or intermittent lighting
• External or internal resistor arrangement
The LED voltage and switch contact rating are separate specifications and should not be confused.
Multiple Button Colors
The A600 Series is available with a broad selection of button colors:
• Red
• Green
• Blue
• Yellow
• Orange
• White
• Black
• Gray
Different colors can be used to distinguish equipment functions or organize groups of controls.
For example:
• Red may be used for stop, warning, or fault-related functions
• Green may identify start, ready, or normal operation
• Yellow may be used for caution or attention
• Blue may identify a special or auxiliary function
• Black, white, and gray may be selected for neutral control functions
Color meanings should remain consistent throughout the complete equipment interface.
Button color alone should not be the only identification method for important functions. Labels or symbols may also be required.
Round and Square Button Options
The A600 Series can be supplied with round and square button designs.
Round buttons provide a conventional control appearance and are easy to integrate into many panel layouts.
Square buttons can help organize closely arranged functions and create clearer visual alignment in equipment interfaces.
Both designs use a glossy actuator surface, which gives the A600 Series a distinct appearance compared with push buttons using a matte surface.
Glossy A600 and Matte A400: Different Appearance Options
The A600 and A400 12mm push button switches serve similar compact panel applications, but they provide different actuator finishes.
A600 Series
• Glossy button surface
• PA66 nylon housing and actuator
• Wire-lead fully sealed option
• Round and square button choices
• Multiple colors
• Illuminated and non-illuminated versions
A400 12mm Series
• Matte button surface
• Different visual and tactile appearance
• Metal housing option available on selected versions
The choice between the A600 and A400 should not be presented as one series being universally better.
The correct selection depends on:
• Desired panel appearance
• Housing preference
• Environmental requirements
• Wiring method
• Operator interaction
• Equipment design
Customers seeking a glossy nylon actuator and sealed wire-lead configuration may prefer the A600 Series.
Customers requiring a matte actuator appearance or metal housing option may consider the A400 12mm Series.
Standard Electrical Rating
The standard electrical rating of the A600 Series is:
• 2A 250VAC
• 4A 125VAC
Customized higher-current versions can be evaluated with ratings up to:
• 4A 250VAC
• 6A 125VAC
The correct version must be selected according to the actual load.
Equipment manufacturers should confirm:
• Operating voltage
• Current
• AC or DC load
• Resistive or inductive load
• Motor, lamp, or solenoid inrush
• Switching frequency
An AC rating should not automatically be treated as an equivalent DC rating.
For loads with high inrush current or inductive characteristics, sample testing in the actual circuit is recommended.
Silver-Plated Contacts
The A600 Series uses silver-plated contacts as the standard configuration.
Silver-plated contacts are suitable for common equipment control and power-switching applications within the specified rating.
Gold-plated contacts can be customized for applications such as low-current or signal-level circuits where a different contact surface may be preferred.
Contact material should be selected according to the actual current, voltage, load type, and operating environment.
Gold-plated contacts should not automatically be considered superior for every application. Their value is greatest when matched to an appropriate low-current circuit.
IP67 Front-Panel Sealing
Standard terminal versions of the A600 Series provide IP67 front-panel sealing when correctly mounted.
This means the switch structure located above the installation panel is protected under the specified sealing conditions.
Front-panel protection depends on:
• Correct mounting-hole dimensions
• Proper O-ring installation
• A flat panel surface
• Correct mounting hardware
• Suitable tightening
• Appropriate panel thickness
The IP67 rating should not be interpreted as full protection of exposed rear terminals.
For applications where only the front of the control panel is exposed to water or dust and the rear remains inside a protected enclosure, the standard terminal version may be suitable.
Fully Sealed Wire-Lead Version
For applications where the rear of the switch may also be exposed to water, moisture, dust, or contaminants, the A600 Series can be supplied with a fully sealed wire-lead structure.
The standard wire configuration is:
• Wire gauge: AWG18
• Wire length: 160mm
The sealed wire-lead version can help:
• Reduce customer wiring steps
• Protect the rear connection area
• Improve integration into wiring harnesses
• Reduce exposed terminal connections
• Support installation in demanding equipment environments
Wire length, wire color, and connector options may be customized according to project requirements.
The complete wiring system still needs to be evaluated. An unsealed connector at the opposite end of the wire can remain a possible entry point for water or contaminants.
PA66 Nylon Construction
The A600 housing and button actuator are made from PA66 nylon.
This construction provides a lightweight, electrically insulating solution for compact equipment controls.
Main material information includes:
• Housing: PA66 nylon
• Button actuator: PA66 nylon
• Nut: Brass
• Contacts: Silver-plated
• Optional contacts: Gold-plated
• Sealing component: O-ring
The nylon structure also supports multiple button colors without requiring a metal surface finish.
Two Connection Options
The A600 Series supports two principal connection methods.
2.8mm Solder Lug
The 2.8mm solder-lug version provides a compact rear connection.
It is suitable for customers with a controlled soldering process and sufficient protection behind the panel.
AWG18 Wire Leads
The wire-lead version uses AWG18 wires with a standard length of 160mm.
It can reduce assembly time and support direct integration into the equipment wiring harness.
The final connection choice should consider:
• Production volume
• Rear-panel space
• Soldering capability
• Wiring-harness design
• Environmental exposure
• Service and replacement requirements
