This article presents a new solution of a vacuum interrupter with electrical contacts in normally open position, used in the construction of switching equipment's for electric power systems, especially vacuum contactors and vacuum circuit breakers for low and medium voltage. It will be described the design, the operating principle and the computerized model. The main advantages of the proposed solution are: high operational reliability, lack of the insulating element in the switching zone
