    Please forgive my ignorance but I’m retired and truly a complete noob. I’m looking to find and match a battery-operated, 12v digital or analog timer with a simple drop bolt lock, like a door bolt, such that a time may be set to send a signal to the drop bolt to open at that time. It may be as simple as a pool timer but again, I‘m a novice in electronics. I was thinking of something like a landscaping transformer but I think that provides a continuous electrical flow to the lock for a specified time and I don’t think that’s what I need. I believe I need a device that sends something like a .5 or 1 second pulse to trigger the bolt to recede or “open” and then return to its original “closed” state.

    Garden tap timers such as the Holman shown below are a basic pulse arrangement.
    Actually current consumption is rather small and they operate on a small 9v smoke alarm battery for months on end.

    Problem there is, expensive and also one would need some electronics experience to hack into the guts and extract whatever you need and then interface it through some external device to your lock mechanism whatever that might be.

    Even using off the shelf timers would require the latter.

    It may be possible to get your device via a locksmith however, in my experience they charge like scrub bulls also.

    More detail on your exact application might bring other options forward.
