Aqua Switch Waterproof Capacitive Touch Buttons Stable PCAP Touch Interaction in Wet and Harsh Conditions

Aqua Switch Waterproof Capacitive Touch Buttons

Stable PCAP Touch Interaction in Wet and Harsh Conditions

Water exposure remains one of the most critical challenges for capacitive touch interfaces used in outdoor and industrial environments. Rain, splashing water, cleaning processes, and condensation can easily disrupt touch accuracy and cause false triggering.

Aqua Switch waterproof capacitive touch buttons from DINGTouch are designed to maintain precise and consistent touch performance in these conditions, ensuring reliable operation even when water is actively flowing across the surface.

Touch Reliability Where Conventional PCAP Fails

Standard projected capacitive (PCAP) touch buttons typically rely on mutual-capacitance sensing, which is highly sensitive to liquid interference. When water forms a film or moves across the touch surface, it may be detected as unintended input, leading to:

• Accidental activation

• Missed or delayed response

• Unstable user control

• Reduced operational safety

Aqua Switch overcomes these limitations through a fully optimized touch architecture, including electrode design, sensing methodology, controller hardware, and firmware-level signal processing. The result is a touch interface that remains dependable in real-world wet environments.

IPX5-Level Waterproof Performance for Active Touch Operation

Unlike solutions that focus only on sealing, Aqua Switch is engineered for active user interaction under water exposure.

By adopting self-capacitance PCAP sensing technology, Aqua Switch achieves strong resistance to liquid-induced electrical noise:

• Reliable operation under 12.5 L/min direct water spray

• Performance equivalent to IPX5-level water resistance

• No false touch during continuous water flow

• Consistent touch response without latency

This makes Aqua Switch particularly suitable for applications where touch input is required during rain, washing, or high-humidity conditions.

Key Advantages of Aqua Switch

Optimized for Wet and Outdoor Environments

Designed for outdoor equipment, semi-outdoor installations, and industrial systems exposed to moisture.

Responsive Light-Touch Operation

Requires minimal actuation force, improving usability and reducing operator fatigue.

Slide Gesture Support

Enables intuitive control functions such as scrolling, switching, or level adjustment.

Flexible Button Configuration

Supports up to 14 independent touch buttons, adaptable to various interface layouts.

Optional User Feedback

Integration options for LED indicators or buzzers provide immediate visual or audible confirmation.

Built for Industrial and Automotive Applications

Aqua Switch is developed to meet long-term reliability requirements beyond consumer-grade touch solutions:

• Touch controller architecture aligned with AEC-Q100 automotive-grade standards

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

• High tolerance to humidity, EMI, and environmental fluctuations

These characteristics ensure stable performance in demanding industrial and outdoor deployments.

Technical Overview

• Touch Technology: Self-capacitance PCAP

• Interaction: Single-finger touch, slide gestures supported

• Cover Glass Thickness: ≤ 4.0 mm

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

• Interfaces: I²C / UART

• Compliance: IEC 61000, AEC-Q100

Design configurations are available with or without integrated LCD modules.
Dedicated controller boards and IC-on-board customization can be provided according to project requirements.

Application Example: Smart Bus Stops and Outdoor Displays

Low-power ePaper displays are increasingly used in smart bus stops and public information systems. While energy efficient, these displays typically lack built-in touch capability.

By integrating Aqua Switch touch buttons into the display frame, users can perform essential interactions such as:

• Page navigation

• Brightness control

• Interface selection

even during rain or wet weather, significantly improving accessibility and user experience in public outdoor environments.

Typical Applications

Aqua Switch waterproof capacitive touch buttons are well suited for:

• EV charging stations

• Fuel dispensers

• Car wash equipment

• Outdoor kiosks and information terminals

• Industrial control panels and machinery

They can also be combined with standard PCAP touch panels to enhance system-level water resistance and operational stability.
