There are several available solutions for the connection of a mobile robot to the charging station on the market. The tests of two existing systems showed the need for the development of an own system. In this thesis I present the development of a bistable switch system, based on the customers requirements. The main topic of the research is the development of a switching system, which is based on the magnetic force created by an electromagnet. This allows for a quick connection and disconnection from the power line, while at the same time guaranteeing a big enough contact force and various types of contact control. The development process is divided in separate parts, starting with the analysis of system demands and overview of the deficiencies of other systems. This is followed by the creation of simulated models of an electromagnet in a static electromagnetic field, and the measurements of the real model. Based on the results we built a prototype of an electromagnet, containing the elements for extending and retracting electrical contacts. Finally, two control system are described and the tests, with which I presented the compliance of work of the switch system with the requirements.
