An exemplary elevator brake control device includes a relay switch that is associated with a safety chain configured to monitor at least one condition of a selected elevator system component. The relay switch is selectively closed to allow power supply to an electrically activated elevator brake component responsive to the monitored condition having a first status. The relay switch is selectively opened to prevent power supply to the brake component responsive to the monitored condition having a second, different status. A solid state switch is in series with the relay switch between the relay switch and the brake component. A driver selectively controls the solid state switch to selectively allow power to be supplied to the brake component only if the relay switch is closed and the monitored condition has the first status.
