ABSTRACT:
A telephone number index and switch device has a series of magnetic switches which are located in fixed positions with corresponding surfaces disposed along a preestablished path of movement of a card finder associated with cards having names and telephone numbers. A magnetic actuator is carried by the card finder but is not in physical contact with the magnetic switches for successively actuating the magnetic switches. A second switch separate and independent from the magnetic switches is used to complete the automatic dialing once a number is selected from the index and a magnetic switch has been actuated.
