An electromechanical telephone dialer for connection to a conventional telephone system including a dial switchboard matrix having a plurality of columns each with 10 openings, one each of the telephone number digits. A contact strip is secured adjacent each column. An input board has a contact button for each opening, with depressions extending the contact button passed the associated strip. A carriage moves a leaf spring contact over each column to complete the circuit from the depressed button to the strip. A similar interlock board is mounted in stacked relation and has a common switch for each column actuated by the aligned buttons. The circuit boards and a stripping switch are interconnected to sequentially scan each of the columns, with the first column scanned until the appropriate character related contact means is engaged. The carriage is spring reset and coupled to actuate the dialing means. The cycle continues until the last number in the final column is transmitted. A drum timer is connected to initiate a code transmitting cycle, transmit a message, if desired, over the telephone lines and then reset the apparatus.
