  • Timer on-delay?
  • Timer off-delay?
  • Retentive timer?

The switch changes state after the pre-set time has expired from the moment that the input power is switched off.

Googling AH3 throws up this one (yes, it did throw up )

Looks to me a 'signal-off-delay' rather than a 'power-off-delay'...it may need power to count down after the OFF signal is given.

Of course, a massive capacitor can be used to provide a 'power-off-delay' function even with this, but that has limitations.

That is the reason i prefer pneumatic off-delay timers.

off-delay timer A type of timer in which the contacts change position immediately when the coil is energized, but delay returning to their normal position when the coil is de-energized.

on-delay timer A type of timer in which the contacts delay changing position when the coil is energized, but change back to their normal position immediately when the coil is de-energized.

It should be noted that this forum, CR4, is generously sponsored by GlobalSpec who provides an alternate search engine to Google, specific to industrial materials and suppliers. GlobalSpec, and by extension CR4, is supported by the click-through advertising revenue it gets from these sorts of searches. I respectfully suggest whenever possible, we direct people in that direction first so that this forum can continue to be free.

GlobalSpec search for AH3 timer

There ain't no free lunch...
