Design of a three-terminal Quantum Switch is suggested in form of a network consisting of a circular quantum well and four semi-infinite single mode quantum wires attached to it. It is shown that in resonance case, when the Fermi level in the wires is close to some energy level in the well, the magnitude of the governing electric field on the well may be specified in such a way that the quantum current across the switch from the up-leading wire to the outgoing wires (terminals) can be controlled via rotation of the orthogonal projection of the governing electric field onto the plane of the device. The details of design of the switch are chosen in dependence of desired working temperature, available Fermi level and effective mass of electron. The speed of switching is estimated. A solvable model of the switch in form of a one-dimensional graph with a resonance vertex is suggested.
