Capacitive Touch Switch

🔹 Type: Momentary

• Touch = ON (output HIGH)

• Release = OFF (output LOW)

• It behaves like a pushbutton that only stays active while being touched.

🔹 How It Works

• Uses capacitive sensing (your body changes the circuit’s capacitance).

• No mechanical movement.

• Detects touch through non-metallic materials like:

  • Plastic

  • Glass

  • Wood veneer

  • Thin paper

This allows you to hide it behind panels for a clean, modern look.

🔹 Electrical Behavior

• Normal state: Output LOW

• Touched: Output HIGH

• Idle for 12 seconds: Enters low-power mode automatically

• Very low standby power consumption

🔹 Physical Features

• 4 × M2 mounting holes for easy installation

• The pad area (or even VCC/GND leads) can act as the touch electrode

• Can replace traditional mechanical buttons

🔹 Typical Uses

• DIY electronics projects

• Arduino / microcontroller inputs

• Hidden wall switches

• Decorative lighting controls

• Appliance control panels
