PROBLEM TO BE SOLVED: To prevent chattering in a switch element even when chattering occurs in a push switch. SOLUTION: This electronic switch is provided with a push switch 2, a flip- flop circuit 1 and a switch element 3. An input terminal 11 of the flip-flop circuit 1 is connected through a second voltage divider resistor R2 to the (-) side of a power source and also connected through the serially connected push switch 2 and a first voltage divider resistor R1 to the (+) side of the power source. A first voltage divider capacitor C1 is connected to the first voltage divider resistor R1 and a second voltage divider capacitor C2 is connected in parallel to the second voltage divider resistor R2. The flip-flop circuit 1 has a control terminal 14 and when a rise voltage is inputted while the control terminal 14 is 'H', output is switched to 'H'. When the rise voltage is inputted while the control terminal is 'L', output is switched to 'L'. The control terminal 14 is connected through an integrating capacitor C3 to the(-) side of the power source and also connected through an integrating resistor R3 to an inverted output terminal 13. |
