DESIGN AND CONSTRUCTION OF A TOUCH-ACTIVATED SWITCH

Abstract

A touch activated switch Is made up of several components interconnected to give the desired output. And the main task in constructing such an electronic device is the incorporation of the respective components together on a veroboard and making sure it functions properly. To realize this a bottom up approach was employed, i.e first unders~anding the basic principles governing the operation of electronic circuits, to the final/complete construction of the circuit. The application of transistors is not limited solely to the amplification of signals, it can be used as a switch. Thus, this project work undertook the design and construction of a simple transistorized switch that can be activated by the touch of the finger. It is adequate for controlling simple domestic appliances, such as lights, fans, etc.
