DISPOSITIF D'INTRODUCTION DE DONNEES DANS UN MICRO-PROCESSEUR

摘要

Device with potentiometer (12) or the like for inputting data into a microprocessor, in particular for a machine for domestic use. The potentiometer (12) is fed by an alternating signal proportional to the signal from the mains supply and the signal at the terminals of this potentiometer is applied to a control electrode of a controlled circuit breaker (18) such as a transistor which transmits a signal with constant level to the data input (21) of the microprocessor (11) when the signal at the control electrode exceeds the conduction threshold (Vbe) for the circuit breaker.
