Long-press fast-clock circuit using relays.
When the button is pressed, the output is linked to the button.
When the button is held down for a long time, the oscillation circuit operates and outputs.
This circuit can be used in the time setting circuit of a clock.

Where's the button?

There is a C-contact button at the top of the first. It is next to the left of the 13kΩ resistor. It's hard to tell because it's mixed in with the relay contacts, lol.

The circuit is such that a single press of the button outputs the output as it is, and a long press activates the oscillation circuit.
