Explore the versatile Custom Symbol Metal Push Button Switch with 1NO1NC/2NO2NC contacts, IP67 waterproofing, and multi-color LED options. Discover real-world applications in marine, automotive, and industrial control systems.
In the world of human-machine interfaces, the push button is your primary point of interaction. But not all buttons are created equal. Whether you are designing a heavy-duty industrial control panel, a custom automotive dashboard, or a marine navigation station, you need a switch that is as flexible as it is durable.
The latest Custom Symbol Electronic Switch series—available in aluminum oxidation black, red, and blue finishes—offers unprecedented versatility. With mounting options ranging from 16mm to 30mm and contact configurations up to 2NO2NC, this switch is engineered to meet the demands of virtually any application.
Here is why this switch series should be your go-to choice for your next project.
Unmatched Electrical Versatility
One of the standout features of this switch series is its ability to handle both resistive and inductive loads across a wide voltage spectrum.
Wide Voltage Range: With a switching voltage from 1.5V to 250V AC/DC, this single switch can handle everything from low-voltage logic circuits to main line voltage.
Contact Configurations: Unlike basic switches that offer only a single pole, this series provides 1NO1NC (SPDT) and 2NO2NC (DPDT) options. This allows you to control multiple circuits or create complex interlock systems with a single button press.
Current Ratings: It handles resistive loads up to 5A at 250V and inductive loads up to 1.25A, making it suitable for small motors and solenoids.
Advanced Illumination and Customization
In modern design, a button must communicate status, not just accept input. The LED options on this switch are industry-leading.
Multi-Color LED Support: Choose from single-color, two-color, or RGB (Red-Green-Blue) illumination. You can even opt for common anode or common cathode configurations to match your PCB design.
Voltage Flexibility: LED beads are available from 1.8V to 220V AC/DC. Note: The 1.8V option is available for red and yellow illumination only.
Custom Symbols: The “Custom Symbol” feature allows you to embed power symbols, play icons, or industry-specific markings directly into the button face, reducing operator error in critical tasks.
Built for the Elements: IP68 Option
Environmental resistance is non-negotiable for outdoor or wash-down applications.
Waterproof Rating: Standard models offer IP67 protection (dust-tight and immersion up to 1 meter). For more demanding applications, IP68 is customizable, allowing for continuous immersion in water.
Material Science:
Housing: Choose between SUS304 Stainless Steel (corrosion resistance), Brass Nickel-Plated (cost-effective durability), or Anodized Aluminum Alloy (lightweight and available in black, red, or blue finishes).
Button: The combination of Polycarbonate (PC) and SUS316 Stainless Steel ensures the button face resists impact and chemical corrosion. SUS316 offers superior resistance to chlorides found in marine environments.
Real-World Application Case Studies
1. Marine Navigation and Control Systems
Challenge: Saltwater corrosion and constant vibration.
Solution: The SUS316 stainless steel button combined with an anodized aluminum housing (blue finish) resists salt spray corrosion. The IP68 customizable option ensures the electronics survive deck wash-downs.
Use Case: Activating bilge pumps, navigation lights, or horn systems on a yacht. The RGB LED can be programmed to change color based on bilge water level (Green=OK, Red=High).
2. Automotive Off-Road Dashboards
Challenge: Dust, mud, and the need for tactile feedback in a jolting vehicle.
Solution: The 2NO2NC (DPDT) configuration allows one button to simultaneously turn on auxiliary LED light bars and switch the dashboard indicator light. The IP67 rating keeps mud and dust out.
Use Case: Control panels for Jeeps or overlanding vehicles for activating winches, lockers, and auxiliary lighting.
3. Industrial CNC and Milling Machines
Challenge: Coolant spray (conductive fluids) and high-vibration environments.
Solution: The Silver Tin Oxide (AgSnO2) contacts ensure a long electrical life even when switching small inductive loads like coolant pumps. The IP67 front panel seal prevents coolant from seeping into the electrical cabinet.
Use Case: Emergency stop (with custom symbol) or cycle start buttons on a CNC milling machine.
4. Public Kiosks and Access Control
Challenge: Vandalism and 24/7 operation.
Solution: The stainless steel construction and mechanical life of >1,000,000 cycles ensure the button can withstand millions of presses without failure.
Use Case: Entry/exit buttons for secure office doors or ticket dispensing machines at train stations.
Technical Highlights
Electrical Life: >500,000 cycles (DC-13 12V 0.5A)
Mechanical Life: >1,000,000 cycles
Contact Resistance: <50mΩ (ensuring minimal power loss)
Insulation Resistance: ≥100MΩ at 500VDC
Dielectric Strength: 2500VAC (safety assured)
Actuation Force: Comfortable 2.5~4N tactile feedback
Conclusion
The Custom Symbol Metal Push Button Switch is more than just a component; it is a design solution. With its robust construction, flexible contact arrangements, and virtually limitless customization options (from LED color to housing finish), it adapts to your specific application rather than forcing you to adapt to it.
Whether you are building a rugged off-road vehicle, a sensitive medical device, or a heavy industrial press, this switch series delivers the reliability and aesthetic you need.
