Aqua Switch Waterproof Capacitive Touch Buttons

Aqua Switch Waterproof Capacitive Touch Buttons

Reliable PCAP Touch Control for Wet and Harsh Environments

In outdoor equipment, industrial control systems, and public infrastructure, water is one of the biggest challenges for touch interaction reliability.

Conventional projected capacitive (PCAP) touch buttons offer basic water resistance, but when exposed to heavy water flow, rain, splashes, or continuous moisture, they often suffer from false touches, unstable operation, or complete touch failure.

Aqua Switch waterproof capacitive touch buttons by DINGTouch are engineered specifically for these demanding conditions, delivering stable, accurate, and responsive touch performance even under running water.

Designed to Eliminate False Touches Caused by Water

When water accumulates or flows across a PCAP surface, the touch controller may misinterpret the water as a valid touch input, resulting in:

• False triggering

• Unresponsive buttons

• Unstable user interaction

• Poor user experience in real-world environments

Aqua Switch addresses these issues through a comprehensive redesign of the touch structure, sensing method, hardware architecture, and firmware algorithms, significantly reducing liquid-induced electrical noise.

Excellent Waterproof Touch Performance (IPX5-Level Water Resistance)

Aqua Switch adopts self-capacitance sensing technology, offering outstanding immunity to water interference:

• Stable operation under 12.5 liters per minute of direct water spray

• Equivalent to IPX5 water resistance performance

• No false touch detection during continuous water flow

• Accurate and reliable touch response at all times

This makes Aqua Switch an ideal solution for environments exposed to rain, splashing water, washing processes, or condensation.

Key Features of Aqua Switch

• Optimized for wet environments
  Suitable for outdoor, semi-outdoor, and industrial applications

• Light-touch activation
  Responsive operation with minimal force

• Slide gesture support
  Enables intuitive interaction such as scrolling, page switching, or level adjustment

• Up to 14 configurable touch buttons
  Flexible layout design for various product requirements

• Optional LED indicators or buzzer integration
  Provides clear visual and audible feedback to users

Industrial-Grade and Automotive-Ready Reliability

Compared with standard PCAP touch buttons that are easily affected by water, Aqua Switch is built for long-term stability in harsh environments:

• Touch controller IC designed to meet AEC-Q100 automotive-grade requirements

• Wide operating temperature range: -40°C to +85°C

• High resistance to humidity, temperature variation, and electromagnetic interference

Technical Specifications

• Touch Technology: Self-capacitance PCAP touch buttons

• Operation: Single-finger touch, slide gesture supported

• Cover Glass Thickness: ≤ 4.0 mm

• Operating Temperature: -40°C to +85°C

• Interface: I²C / UART

• Compliance: IEC 61000, AEC-Q100

• Design Options:

  • Touch buttons without LCD

  • Touch button modules with integrated LCD

A dedicated controller board is available, and IC-on-board solutions can be provided based on customer requirements.

Outdoor Application Example: Smart Bus Stops and Public Displays

With the increasing adoption of low-power ePaper displays in smart bus stops and public information systems, user interaction remains a challenge, as ePaper panels typically do not support touch input.

By integrating Aqua Switch touch buttons into the display bezel, users can reliably perform actions such as:

• Page navigation

• Brightness adjustment

• Interface switching

even in rainy or wet conditions, significantly improving usability in outdoor public spaces.

Typical Application Scenarios

Aqua Switch waterproof capacitive touch buttons are well suited for:

• EV charging stations

• Fuel dispensers

• Car wash control panels

• Outdoor kiosks and information terminals

• Industrial equipment and control panels

Aqua Switch can also be combined with standard PCAP touch panels, ensuring stable and accurate touch performance even when water is present on the surface.
