PURPOSE:To eliminate the chattering of a switch with good response by providing an inverting circuit and a monostable multivibrator to an output side of the switch and applying this output and the switch output to a logical gate for processing them. CONSTITUTION:In turning on/off a switch 15, a chattering is generated at the application and interruption and outputted to an output terminal 11 of the switch 15. This voltage waveform (a) is applied to one input of an OR gate 18 and also to an NOT gate 16 and an inverted voltage waveform (b) is extracted at the output of the NOT gate 16. This voltage waveform (b) is applied to an edge trigger monostable multivibrator 17, and a voltage waveform (c) is extracted from the output and applied to other input of the OR gate 18. Thus, a voltage waveform (d) eliminating the chattering is extracted at an output terminal 12 of the OR gate 18. |
