The present disclosure refers to a waveguide electromechanical relay switch having a rotor with transmission paths and an axis of rotation parallel to the base plane combined with an actuator adapted to the configuration. A 4-pol switch design enables compensation of fault cases in a relatively shortened length of transmission line, reducing potential RF loss. In one embodiment, a 4-pol rotor includes an offset transmission path that enables crossing of another path on the same rotor, providing increased functionality and fault-case recovery.
