20PCS TTP223 Touch Sensor Module, Capacitive Touch Switch with SelfLocking Function for Arduino

TTP223 Capacitive Touch Switch Button Sensor Module SelfLocking Available in packs of 20, 50, or 100 pieces Key benefits Simple, intuitive touch control that replaces mechanical push buttons. Selflocking output toggles on and off with each touch, making it easy to implement latching controls without extra code. Small module form factor and digital output enable straightforward integration into electronics projects and control panels. options available to fit specific project needs. What it does Capacitive sensing module based on the TTP223 model for touch detection. Provides a digital module output that changes state when the sensor pad is touched. Designed for repeated, reliable operation while keeping wiring and component count low. Important attributes Model: TTP223 Sensing theory: capacitance sensor Function: selflocking touch switch module Material: constructed from a mixture of materials for the module and components Output: digital module output for direct interfacing : configurable options available as indicated by product listing Why customers need it Replaces mechanical switches in user interface designs to improve durability and ease of cleaning. Saves space and simplifies wiring in compact or multibutton layouts. Useful where a latching touch input is preferred, such as toggling lights or modes without holding the sensor. Practical use scenarios Home automation panels: use as touch toggles to switch lights, fans, or other household devices through a control system. DIY electronics and prototypes: integrate into microcontroller projects as compact, reliable user inputs for menus, mode selection, or power control. Interactive displays and kiosks: provide a lowprofile, durable touch interface for public or commercial installations. What to expect in integration A straightforward digital signal that can be read by microcontroller boards, logic circuits, and other control systems. Compact modules that can be mounted under user interface surfaces or on small PCBs. Consistent touch response using capacitive sensing, with the convenience of selflocking behavior for toggle functions. This product is offered as sensor modules in multiunit packs to support batch installations and repeated use in projects and production.
