Abstract

The key uses manually input pulses which must also be produced in correct order. This method eliminates the possibility of unauthorised persons finding out a given code by experiment. The first output stage only produces an output signal if the data which has been manually inserted by means of a push button arrangement is correct. The circuit has 9 pulse generating keys J1 - J9. This system operates with a four figure code. The coding printed circuit St is inserted between the switches and the actuators L0-L5. The circuit includes further transistors and pulses are generated for the following circuit with amplifiers for power actuators.
