Description:
Touch Switch Sensor Module Double sided TouchPad 4p/3p Interface
This is a touch switch sensor module featuring a double-sided touch pad with a 4-pin or 3-pin interface.
Note: Product may vary from images shown in terms of brand name according to the availability.
Features:
- This device has two compatible interfaces: a 2.54mm 3-pin interface and a 4-pin Grove interface.
Note: The pins are labeled as follows: S for the digital output port that varies with voltage, N for the unused pin, V for the common collector voltage, and G for the ground. The digital output is VDD when the button is not pressed, and 0V when the button is pressed down.

Touch Switch Sensor Module Double sided TouchPad 4p/3p Overview
The Touch Switch Sensor Module Double sided TouchPad 4p/3p is a capacitive touch switch board featuring a dual-sided touch pad and two interface options. It delivers a clean digital output that goes low when touched and high when idle, making it ideal for compact control panels and finger-activated inputs.
Key Features of Touch Switch Sensor Module Double sided TouchPad 4p/3p
- Dual-sided copper touch pad for versatile mounting and orientation
- Selectable 3-pin (2.54 mm) or 4-pin Grove interface for easy integration
- Digital output (S) reads VDD when untouched and 0 V when pressed
- Wide supply voltage of 3.3 V–5 V with ultra-low working current (18 μA at 5 V)
- Standard header pins labeled S, N (unused), V, G for straightforward wiring
- Genuine product, fast shipping from Zbotic with order tracking
Applications and Use Cases
- Touch-activated user interfaces on Arduino and Raspberry Pi projects
- DIY home automation panels for lighting or appliance control
- Interactive art installations requiring slim, responsive touch inputs
- Robotics control modules for triggering actions or modes
- Custom electronic devices where a mechanical switch footprint is undesired
How to Use Touch Switch Sensor Module Double sided TouchPad 4p/3p
Connect V to your 3.3 V–5 V supply, G to ground, and S to a digital input pin on your microcontroller. Ignore the N pin. Once powered, the module will output a HIGH level at S until you touch either side of the pad, at which point it switches to LOW. Mount the board on a stable surface and wire it via breadboard or Grove cable for quick prototyping.

Frequently Asked Questions
Can I use both the 3-pin and 4-pin interface simultaneously?
No, you should choose either the 3-pin header or the 4-pin Grove connector. The 3-pin provides S, V, G, while the 4-pin adds an unused N pin alongside S, V, G.
What voltage levels does the touch switch output?
The digital output (S) matches the supply voltage (3.3 V–5 V) when the pad is not touched. When you press the touch pad, the output drops to 0 V.
How do I mount the touch pad for reliable operation?
Secure the module on a non-conductive surface using screws or adhesive. Ensure the copper pad is unobstructed and wire V, G, and S firmly to your controller’s headers or via a Grove cable.
