A switch for selectively routing electrical signals, particularly microwave signals, in a printed circuit board includes a rotatable contact that is connected to a shaft. A first motor is configured to rotate the shaft and a second motor is configured to axially move the shaft to lift the contact from the printed circuit board. A position controller produces driving signals that are received by the first and second motors to lift the contact from the printed circuit board, rotate the contact to a desired position and lower the contact to the circuit board.
