3V-30V Touch Key Switch Sensing Module

The DC3V-30V Touch Key Switch Sensing Module (4-Wire) is a versatile and user-friendly solution for LED lighting, DIY electronics, and interactive projects. This bistable touch-sensitive switch allows users to control devices with a simple touch, replacing traditional mechanical switches and providing smooth, silent operation.

Designed for compatibility with LED light bands, lamps, and low-voltage DC electronics, this 4-wire touch module offers jog and latch modes to suit a wide range of applications, making it ideal for DIY hobbyists, engineers, and home automation enthusiasts.

Key Features:

• Wide Voltage Compatibility
• The module operates efficiently across a DC voltage range of 3V to 30V, making it suitable for various LED lighting systems, low-voltage DC
• electronics, and battery-powered projects. This wide voltage range ensures reliable operation for both small LED strips and larger DIY electronics.

4-Wire Design:
The 4-wire configuration provides separate input and output lines for simplified installation and stable operation:

• VCC – Connects to DC positive supply
• GND – Connects to DC ground
• OUT+ – Positive output for the load
• OUT- – Negative output for the load

This configuration enhances safety, flexibility, and ease of integration in various circuits, making it ideal for professional and DIY setups.

Bistable Touch Function:
The bistable design ensures that each touch toggles the output:

• First touch: Turns the device ON
• Second touch: Turns the device OFF

With touch-sensitive control, the module eliminates mechanical wear, providing long-lasting, reliable performance for continuous use.

Jog and Latch Modes:
This touch module supports both jog (momentary) and latch (bistable) modes, allowing flexible operation:

• Jog mode: Device remains ON only while the sensor is pressed
• Latch mode: Device toggles between ON and OFF states with each touch

This versatility makes it perfect for LED strips, home lighting, and interactive electronics.

Touch Sensing Technology:
The module employs capacitive touch sensing, which detects a light finger press. No mechanical force is required, ensuring silent, smooth, and responsive operation.
