ABSTRACT:
Improved telephone number input terminal devices for memory stored dialing data for automatic dialing have a divided housing (12) with an upper section (13) that is readily attached to and removed from a base section (14) so that a printed circuit board (61) which carries a plurality of electric elements (17) may be made inexpensively and readily assembled. A single electric element (51) is carried on the card finder (25) which is slidable on and retained by an enlarged end portion of the cover (22) for the index cards. Light emitting diodes and Hall effect devices are examples of preferred electric elements that may be used in the switch means to effect the electric switching required.
