TTP223 Touch Key Switch Module Touching Button Self-Locking/No-Locking Capacitive Switches Single Channel , Multicolor

the module is small but very good working good touch sensitivity and good build quality

Low quality perfect Performance

Tiny product, but works beautifully. User must be a geek or experienced hobbyist to use this. Good to use where built in switch is inaccessible or hard to use.

Some are working automatically

module works fine, bear in mind this one has a and b jumper point to be soldered in case you want to change switch beviour from hold touch to toggle touch control. Led is on the back side so you cannot use it at the front facing touch panel side. Soldering jumpers may be difficult as the points are not populated with any through pins but yes they do provide pins for the backside interface which you can repurpose, works fine as intended. No issues whatsoever. tested on 5V.

Only on 1 pcs comes in delivery and after I replaced it again only 1 pcs comes wrost experience.

I mean either my Hands are too big or The Switch sensor are too small 😂🤦🏻‍♂️As you can see in the images. It’s so tiny that when i opened the Package. I thought there’s nothing in there 🤣. Thought i was scammed. Just a bubble wrap. When i saw something. I thought it must be just one peice. But as i got it opened. Shocked to see it so small. It’s like 1cm wide and 15mm length. 😂. Surprisingly shocked. Happy to receive early as expected. Haven’t tested it. Yet. But will update soon. For the price being. It looks expensive still. But okay.

The price is a bit high compared to other sites and apps but the product is good I recommend to buy it
