Abstract
A switching circuit with a time-delay device comprises a pulse generator, and a counter which receives pulses therefrom. The overflow output of the counter transmits a counter signal after receiving a predetermined number of pulses. The counter is provided with a holding circuit for maintaining the counter signal up to the time of resetting and renewed start of the counting operation. The resetting input of the counter receives a signal either by way of an inverter or directly. The overflow output of the counter is connected with the output of the time delay device, either directly to obtain a delayed start or by way of an inverter to obtain a delayed termination.
