Just be ready to solder. It doesn’t come with pre soldered connectors Review: 1 year review. Work as advertised. I have them under both a sheet of acrylic and thin cardboard and they still work fine. Observations. When configured as non latching they only stay on about 2 seconds when held. When configured as latching they output for extended periods. Very sensitive. You don’t actually have to touch to activate. Output is only 4v when operating on 5v which is fine for most logic circuits. Output switches between 4v and ground which is nice because I don’t need pull up or pull down resistors on the Arduino side of the circuit (recommend adding then anyway if your wire runs are long, mine are all less than 7”). However a few of them failed when supposed to output ground and had to be replaced, but that could be due to my initially poor soldering skills (which have improved considerably.) When configured for ground output the LED stays on when not activated. Finally you need to supply and attach your own headers, but that allows you to choose both the orientation and type of connection. I’ve soldered both wires and headers to them without issue, save for the possible failures mentioned above. Overall very satisfied. ## Features - The module is based on a touch-sensing IC TTP223 capacitive touch switch module, it allows you to avoid the trouble of conventional push-type buttons. - Size: 15*11mm - Modes: jog, self-locking - Power Supply: 2.5V-5.5V - Package Include: 20PCS TTP223 Capacitive Touch Switch Sensor ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | ALAMSCN | | Product Dimensions | 1 x 1 x 1 cm; 9 g | | Manufacturer | ALAMSCN | | Color | Red | | Are Batteries Included | No | | Item Weight | 9 g | ## Product Details - **Brand:** ALAMSCN - **Circuit Type:** 2-way - **Connector Type:** Pin Header - **Contact Type:** Normally Open - **Item dimensions L x W x H:** 0.39 x 0.39 x 0.39 inches - **Material:** Copper - **Mounting Type:** PCB Mount - **Operation Mode:** ON-OFF - **Switch Type:** Touch Switch - **Terminal:** Through Hole ## Images ![TTP223 Capacitive Touch Switch Button Sensor Module Self Locking for Arduino (Pack of 20) - Image 1](https://m.media-amazon.com/images/I/710fW2HVBBL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***R on 3 January 2026* It works great!

However, it works WELL as a HIGH/LOW signal when using a logic level MOSFET. Not as well with NPN BJT because of the current required. The quiescent current when wired to project and off is 4.3uA, so totally satisfactory for a battery project. Active power (latched on, no project load) with board LED is 7mA. Board LED removed, current when on rises from 4.3uA to only 7uA, which is GREAT low power when active. I've only used the latching function, HIGH to turn on. Does in fact trigger without quite touching. They are SMALL, so if wanting a decent sized touch pad for other end users, look elsewhere and choose based in dmiensions. Otherwise, I'd recommend having these around to play with projects without using switches and buttons and dealing with debouncing with hardware or code. ## Frequently Bought Together - ALAMSCN 20PCS TTP223 Capacitive Touch Switch Button Sensor Module Self Locking for Arduino… - HiLetgo 10pcs TTP223B Capacitive Touch Switch Module Touch Sensor Switch Digital Capacitive Touch Sensor Switch DC 2~5.5V - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/517254192-ttp223-capacitive-touch-switch-button-sensor-module-self-locking-arduino](https://www.desertcart.ae/products/517254192-ttp223-capacitive-touch-switch-button-sensor-module-self-locking-arduino) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-06-06*
