A hand switch for use with an x-ray machine includes a first switch actuator that starts the prepare sequence of the x-ray machine. Upon completion of the prepare sequence, the hand switch signals the x-ray technologist with a tactile indication that the prepare sequence checks are complete and that the machine is ready for an exposure. The hand switch has a second switch actuator that is used by the technologist to activate the exposure. During the actuation of the first and second switch actuators, the operator may maintain uninterrupted visual contact with the patient.
