ABSTRACT:
This invention relates to a button-type code car-switch controller, especially one which can turn on and off the car switches with the signal sent by the code operating circuit and control circuit formed by such electronic elements as transistor-transistor logic (TTL) and with the alarm interface circuit, can work together with various alarm systems so as to protect the car against thief, robbery and wire cutting-off. While the set code can be changed after the car switch is turned on, the alarm can be activated when a wrong code is keyed in. With this controller the car can be operated without conventional keys.
