Learn the basics of designing and building a Rotary Switch–Selectable Timer for industrial and domestic applications. This project explains how a rotary switch is used to select different time delays, ranging from 10 seconds to 6 minutes, to control an appliance using the CD4060 timer IC. It is ideal for understanding timer selection concepts and their practical use in delay-based appliance control.
