The research examines the printing of passive electrical circuit elements, specifically of printed switches. In the introduction, the functional printing and printed electronics are defined, and the composition and functioning of printed switches are explained. The aim of the research was to create printed switches of different sizes and shapes with screen printing, and to explore the optimal conditions for their operation. In the experimental part, two types of switches were developed, namely with sensors based on two electrodes (electrical capacitor) and sensors based on a single electrode. Various forms of sensors were designed and printed on printing materials (special paper for printed electronic, recycled paper and foil) with functional conductive ink and the screen-printing technology. Printed sensors were varnished and laminated. On each of them, measurements were performed and the influence of various factors was evaluated, i.e. the shape and size of capacitors/electrodes, printing material, air moisture, varnishing and laminating. Finally, the functionality of sensors was analysed and the sensors were applied onto a packaging as switches for turning on an LED light.
