Abstract

PURPOSE:To enable the signal input by manual operation without externally mounted circuits, by using a simple buffer element in the combination of light emitter and photodetector having thermal inertia, for a chattering preventing circuit. CONSTITUTION:A light emitter 2 having thermal inertia is illuminated with on of a switch 5. A transistor 3 makes switching operation with the light of the light emitter and outputs a signal at an output terminal 10. Further, the applied voltage at the power supply terminal 9 of a chatterless switch 1 in applying thermal inertia, is made in coincidence to the high level input voltage of an intergrated circuit, allowing the output from the terminal 10 to be used as the input signal to the digital circuit directly.
