We present an experimental demonstration of a phase qubit acting as an ON/OFF switch for the absorbtion of photons from an applied probe microwave tone. The control of the switch is achieved through a second microwave tone resonantly coupled to the second transition of the qubit. The ON state is realized when the control tone is sufficiently strong to generate a "dark state" for the qubit, preventing the absorbtion of the probe tone. A three-level model that includes independently determined parameters for relaxation and dephasing gives excellent agreement with the experiment, and allows us to characterize the time-scale for switching.
