TTP223B Capacitive Touch Switch Module
- This is the “momentary” variety of the touch sensor – touch and it turns on, release and it turns off.
- Positive and negative can be used as a touch surface,can replace the traditional touch button.
- Four M2 screws positioning holes for easy installation.Module can be installed in such as surface plastic, glass of non-metallic materials.
- In addition to the thin paper ( non-metallic ) covering the surface of the module , as long as the correct location of the touch , you can make hidden in the walls, desktops and other parts of buttons.
- The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, low power consumption; When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode.

For Engineers Who Love Open Source Hardware
Hello, fellow geeks!
I’m an embedded systems engineer with a degree in IoT Engineering, and I’ve been deeply involved in AIoT product development for years. I’ve participated in several B2B projects from the ground up — covering open-source hardware, system architecture, hardware selection, and solution implementation.
Through this journey, I’ve come across all kinds of AIoT products.
Some are smart, efficient, and elegantly designed; others are overcomplicated, packed with features that don’t solve real problems.
Over time, I’ve started focusing on one simple but important question:
Does this product truly solve the user’s core need?
Not just whether it’s ‘cool’ or uses the latest tech.
I firmly believe that great products don’t have to be complex or expensive — they just need to solve problems clearly and effectively, at a reasonable cost.
That’s why I created this site:
A space where engineers can connect, share, and learn from each other.
Here, I share great products and smart solutions I’ve encountered during projects — and try to explain why they’re good.
This isn’t about marketing. It’s about real experience, honest judgment, and technical clarity.
This platform is called sharingwin, because I believe in shared success.
You’ll find high-value, practical tools and products here — to help you save time on selection, avoid unnecessary trial and error, and focus on what works.
As for me, I hope to use this space to connect with like-minded engineers, exchange ideas, and — to be honest — maybe earn a little on the side too. That’s part of the fun. 😄
To all the makers and creators who’ve supported me along the way — thank you.
Due to some heavy personal projects recently, I haven’t been able to update or engage as frequently as I’d like — and for that, I apologize.
Moving forward, I’ll continue to optimize product content and be more active in sharing useful insights.
Your trust and support mean everything.
You’re the reason I believe this platform matters.
If you have any great products or ideas you think deserve more visibility, feel free to reach out.
I’m happy to help with sourcing, connect to the right supply chain, or feature it here so more engineers can see its value.
A single person has limited power —
but co-creation multiplies value.
If you believe in that too, let’s build something useful and meaningful — together.
This module is a capacitive momentary touch switch module based on the touch detection IC (TTP223B). Under normal conditions, the module outputs a low voltage, operating in low power mode.
When you touch the designated area with your finger, the module will output a high voltage, switching to fast mode.
If there is no touch for 12 seconds, the module switches back to low power mode. The module can be installed on non-metallic surfaces such as plastic or glass. Additionally, you can cover the module with a thin layer of paper (non-metallic) until the touch position is correct, allowing the module to function as a hidden button on walls, desks, or other places. This module eliminates the need for conventional mechanical press-type buttons.
Features:
- Low power consumption
- Power supply: 2 ~ 5.5VDC
- This module can replace the traditional touch button
- Four M2 screw positioning holes for easy installation.
Control Interface: There are 3 pins (GND, VCC, SIG).- GND is the ground.
- VCC is the power supply.
- SIG is the digital signal output pin.
- Power Indicator: Green LED, which lights up when the power is correctly supplied.
- Touch Area: The area inside the fingerprint-like icon, where a light touch with your finger can trigger the module.
- Positioning Holes: Four M2 screw positioning holes, with a hole diameter of 2.2mm, designed for easy installation and positioning of the module, allowing for the combination
