  • Patent number: 5495525
    Abstract: A telephone having a non-volatile circuit for automatically dialing 911 upon depression of a single key includes an oscillator activated in response to depression of the key for transmitting clock pulses to a counter. Certain of the output signals from the counter are applied to switches in sequence. The switches are connected to selective column and row leads of the telephone dialer circuit corresponding to the digits in the telephone number to be dialed. The switches short together the respective column and row leads so that the dialer reacts in the same manner it would when the keys of those digits are depressed on the telephone keypad. An output pulse from the counter resets the circuit after the switch connects together the column and row leads of the last digit of the telephone number.
