I'd say that's worthy of a question on the main 'site.

I'm looking for an off-delay timer to switch off a load after a specific amount of time - i.e. "push a button and the light comes on for a while and then goes off". They're often used for bathroom fans, hallway lights and the like, and I'm looking for one that goes on a DIN rail. So far, that's pretty standard -

however, I want to be able to push the button again to immediately turn the light off (i.e. immediately end the time)- but none of the ones that I looked at datasheets for seems to do this. I know I can cancel / reset the timer by removing power to the timer unit, but I want to do this with a single button. Does anyone know name for this, or another way to achieve this if a single device that does it doesn't exist?

@JonasCz-ReinstateMonica I suspect this functionality is more commonly found in wallbox devices

if you were on this side of the pond, I'd throw a Lutron Maestro MA-T51 at the problem, but that's a 120VAC device
