Touch Switch Circuit using 555 Timer | Relay Control for AC Load in Proteus Simulation

In this video, we design and simulate a Touch Relay Control Circuit using the 555 Timer IC in Proteus. This project demonstrates how to control an AC load (220V lamp) with just a simple touch input instead of a mechanical switch. 🔹 How the Circuit Works: A touch plate is connected to a BC547 transistor that senses the human touch. The transistor triggers the 555 Timer IC, which acts as a flip-flop control circuit. The output of the 555 IC drives a 12V relay, which switches the AC lamp (220V) ON or OFF. An LED indicator is also added to show the relay status. 🔧 Components Used in This Simulation: 555 Timer IC BC547 Transistor 12V Relay AC Load (220V Lamp) LED + Resistor Capacitors & Resistors This is a simple and useful project for learning how to design touch-controlled electronic switches and relay driver circuits in Proteus. 👉 Don’t forget to Like, Share, and Subscribe for more electronics simulation projects in Proteus!
