Jonathan Ames Posted August 5, 2020 Report Share Posted August 5, 2020 Please forgive my ignorance but I’m retired and truly a complete noob. I’m looking to find and match a battery-operated, 110v/12v or 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.

HarryA Posted August 5, 2020 Report Share Posted August 5, 2020 You can get timers that will go down to 1 second that maybe helpful. For example: "7-Day Programmable, Minimum Setting Time is 1 Second " https://www.amazon.com/NEARPOW-Multifunctional-Programmable-Countdown-Electrical/dp/B07QJ3K43N/ref=sr_1_118_sspa?dchild=1&keywords=electrical+timer&link_code=qs&qid=1596596156&sourceid=Mozilla-search&sr=8-118-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExRjRDTVBKVFVSMDhIJmVuY3J5cHRlZElkPUEwOTQwNzE4MUlLQVhNSk1WUzg5SyZlbmNyeXB0ZWRBZElkPUEwOTU5OTM3M0dLT0IwMTZDVVpSNyZ3aWRnZXROYW1lPXNwX210ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU= You can also get 110 volt solenoids that would work off the timer. For example. https://www.amazon.com/Dormeyer-Laminated-Solenoid-Arcade-2005-M-1/dp/B00LNB2R5Q/ref=psdc_15731411_t1_B000CCNGMU If you need a dc solenoid you can get a small power supply that works with the timer. For example. https://www.amazon.com/ALITOVE-Converter-110-220V-Cigarette-Purifier/dp/B075FPQ2YQ/ref=sr_1_4?dchild=1&keywords=120+to+12+volt+converter&link_code=qs&qid=1596632952&sourceid=Mozilla-search&sr=8-4&tag=mozilla-20 And 12 volt solenoids are readily available: https://www.amazon.com/RuiLing-JF-0730B-Frame-Solenoid-Electromagnet/dp/B07QTKL4FV/ref=sr_1_23?dchild=1&keywords=12+volt+solenoid&qid=1596659237&sr=8-23 There are 12 volt solenoids that are designed for door latches if that is helpful. For the solenoids: 4.5N (newtons) equals 1 pound of force. Quote Link to comment Share on other sites More sharing options...
Jonathan Ames Posted August 6, 2020 Author Report Share Posted August 6, 2020 Yep, but it seems to me there has to be an easier way. I’m reading up on time delay relays now trying to figure this out. Thanks again for all the help. Quote Link to comment Share on other sites More sharing options...
