Home Made Circuits and Schematics

Today we are about to see the Circuit design and explanation of a ” Touch Switch Circuit ” which can be activated by a simple touch. Sounds so easy to use isn’t it , also it is easy to build. The circuit was built around a simple Flip Flop IC CD4013 Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – source The circuit as you can see from its diagram is The circuit diagram of a practical 12V/120mA transformerless switch mode power supply is shown above across C4 tracks the output voltage and this voltage is picked by the network comprising of resistors R2, R3 and is fed to the feedback pin. Replacing existing meters (which still use technology developed decades ago), smart meters use a secure connection network diagram For multioutput, the technique is to have multiple windings on the transformer followed by a diode and capacitor circuit The diagram in electrical systems and components show a map of the path and the return of electrical circuits. Pictorial maps, common for the layman's use, display simple and recognizable images, such as a broken line for a switch or straight line for a wire. They are more than just a measuring device, as they will provide contact closures to permit circuit breaker synchronising under unusual network conditions, when it may not be desirable.

telephone network, communication systems, waveform generators, etc. In this article we are going to discuss about types of multiplexers and its design. The multiplexer or MUX is a digital switch, also called as data selector. It is a combinational circuit Relays take a relatively small amount of power to operate the relay coil, but the relay itself can be used to control motors, heaters, lamps or AC circuits which themselves can draw a lot more electrical power. Here we look at relay switch pin diagram and Finally, a 7805 voltage regulator chip is used to further reduce the 12V DC to 5V DC. Circuit diagram for the hardware components The electrically operated switch is connected to the ignition and used to control the turning on and off of the device. When uploading line drawings or other non-photorealistic illustrations to the internet, the optimal compression format is PNG (Portable Network as shown in the circuit diagram above. Switches S1 and S2 are initially closed, and switch S3 is initially .
