Description

Touch Sensor Switch Module is a capacitive touch input board that works like a button—just touch the pad to trigger an output signal. It’s ideal for modern touch controls in smart home devices, lamps, appliances, DIY electronics, and microcontroller projects. Compared to mechanical buttons, it offers silent operation, longer life, and a clean user experience.

Key Features

Capacitive touch activation (touch to switch)
Works as a digital touch button (ON/OFF signal output)
Fast response and stable sensitivity
Long life (no mechanical wear)
Easy to use with Arduino, ESP32, ESP8266, STM32, etc.
Compact module size for embedded designs

Full Specifications (Typical)

Exact values may vary depending on the module model (TTP223 or similar).

Electrical

Operating Voltage: typically 2V–5.5V (commonly 3.3V/5V compatible)
Output Type: Digital output (HIGH/LOW)
Output Mode:
- Momentary (active only while touched) or
- Toggle (touch to ON, touch again to OFF) — module dependent / jumper options
Current Consumption: low power (ideal for battery devices)

Module Pins (Common)

VCC – power input
GND – ground
OUT / SIG – digital output signal

Touch Operation

Touch pad can be used directly or through a thin non-metal cover (plastic/glass)
Sensitivity depends on pad size, wiring, and mounting surface

Applications

Touch lamps and LED control
Smart switches and home automation panels
DIY appliances and control boxes
Door access panels and user interfaces
Arduino/ESP32 touch input projects
Interactive projects and educational kits

Used In

ESP32/Arduino projects (touch as a button input)
Relay control (through transistor/relay module)
IoT devices and smart furniture controls
