This is a combination of a 60 second oscillator with a second timing circuit that puts out a one sec. pulse. (indicator light) lights up for 1 sec.

The whole circuit works as every 60 sec. the LED (indicator light), flashes on for a pulse duration of 1 sec.

It was a fun build project, to see how it could be done,
I did not simulate it, but rather it was built on a breadboard, and it works good, you have to adjust resistor values to get it as precise as needed.

See if this helps any.
Thank you, your circuit is also good.
Can u help me with this problem too? https://forum.allaboutcircuits.com/threads/how-to-ad-switches-to-2-channel-remote.142561/
