PURPOSE:To ensure a sudden inverting action and then secure a steady control action of a switch, by forming the output detecting/inverting part of a timer with an inverter. CONSTITUTION:The inverter 103 has an inverting action in accordance with the relative value of the input signal level to the application voltage and then produces the control signal to control the ON/OFF of the switching device 102. The talking switch 104 makes the inverter 103 control the device 102 when it is active and then puts the talking circuit 101 under the active state. The timer 105 produces the output in response to the switch 104. Then the signal of a certain level is supplied to the inverter 103 for a certain time set previously to actuate the circuit 101 after resetting of the switch 104. Furthermore, the output of the timer is varied within a set time of the timer 105 to give a forced inversion to the inverter 103. |
