Push Button SPST ON-OFF Switch RED
[Mechanical Switches] The Push Button SPST ON-OFF Switch (Red) is a durable and reliable panel mount power control switch designed for electrical and electronic circuits. It features a Single Pole Single Throw (SPST) configuration that allows users to easily turn a circuit ON or OFF using a simple push operation. This switch uses a non-momentary (latching) mechanism, meaning the switch stays in its current state until pressed again. When pressed once, the circuit turns ON, and when pressed again, it switches OFF. This makes it perfect for applications where continuous power control is required. With a rated voltage of 250V AC and current capacity of 3A, the switch is suitable for a wide range of electronics, DIY projects, robotics systems, power supplies, and industrial control panels. The switch is designed for panel mounting, allowing secure installation in enclosures, equipment housings, and control boxes. Its bright red button provides clear visibility and easy identification, while the compact size makes it suitable for both small and large electronic projects. This push button switch is widely used in DIY electronics projects, Arduino systems, industrial machines, appliances, and control circuits where a simple and reliable ON/OFF switching solution is needed. ⭐ Key Features SPST (Single Pole Single Throw) configuration Push ON / Push OFF latching mechanism Non-momentary push button switch Panel mount installation Compact and lightweight design Bright red actuator button Easy wiring with 2 pins Suitable for electronics, robotics, and industrial applications 🔧 Technical Specifications Rated Voltage: 250V AC Rated Current: 3A Number of Pins: 2 Switch Type: Non-Momentary Push Button Action Type: Push ON / Push OFF (Latching) Configuration Type: SPST (Single Pole Single Throw) Mounting Type: Panel Mount Button Color: Red Terminal Type: Pin / Solder Terminal 🎯 Applications DIY electronics projects Arduino and microcontroller circuits Robotics systems Industrial control panels Power supply switching Appliances and electrical devices Automation equipment 📦 Package Includes 1 × Push Button SPST ON-OFF Switch Red
TTP223 Touch Key Module
[Sensors, Touch Sensors] The TTP223 Touch Key Module is based on a touch-sensing IC (TTP223) capacitive touch switch module. A capacitive touch sensor module based on the dedicated TTP223 touch sensor IC. The module provides a single integrated touch sensing area of 11 x 10.5mm with a sensor range of ~5mm. An onboard LED will give a visual indication of when the sensor is triggered. When triggered the output of the module will switch from its idle low state to high (default operation). Solder jumpers allow for reconfiguring its mode of operation to be either active low or toggle output. TTP223 Capacitive Touch Sensor Module.
