- 2. What is a Touch ON and OFF Switch Circuit • Touch ON and OFF Switch is a type off switch that can be used to control any electrical or electronic appliance. • A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor.
- 3. Components used in circuit Diagram • Components Required • 1 x 555 Timer IC • 1 x 3.3 MΩ Resistor (1/4 Watt) • 1 x 1 MΩ Resistor (1/4 Watt) • 1 x Bulb with holder (regular or CFL) • 1 x 5V Relay Module (if relay module is not available, then you need the following components) 555 Timer IC 3.3 MΩ Resistor Bulb with holder 5V Relay Module (if relay module is not available, then you need the following components 2N2222 NPN Transistor 1N4007 PN Junction Diode 1 KΩ Resistor (1/4 Watt
- 5. How to make the Touch Sensor (Touch Plate) As the project is based on a Touch to ON and OFF the devices, Touch Plates or Touch Sensors are an important part of this project. We do not need costly or fancy touch sensors as we will show you how to make a simple touch plate for this project.
- 6. Applications A simple Touch to ON and Touch to OFF Switch Circuit is designed in this project using which, we can turn ON or OFF any device by simply touching the pads. By isolating the touch plates from the actual circuit, we can create a nice looking touch controls for our appliances.
