We can make Single Push Button ON OFF Relay Circuit with one push button to control motor or light. Press button and relay will turn ON and then press again and relay will turn OFF; hence, there is no need of microcontroller or timer IC, so use only some transistors and one capacitor. Circuit Working: […]
