## Description

12V Timer Switch - Programmable, DC/AC/Solar Battery Powered | 12 Volt JVR Timer Relay - desertcart.com

Review: Great timer - Discovered you can even set the seconds for on/off - These are really slick & reliable. I have two - one that I've had for over a year and another I just received. They state up to 16 on/off programs but my new one actually has 28! I use one for cycling 12v power to my wifi router for a nightly reboot. The other I use to cycle 120v power to my laser holiday lights because the laser lights otherwise only stay on for 6 hours. I took the holiday lights down last year and one year later I took them out of storage and the programs and clock were still held in memory and still accurate. As noted the battery keeps the memory but the relay only operates when 12v is applied on the power terminals. But you can cycle off the 12v power as I do with my holiday lights at dawn, then when 12v is reapplied (at dusk) the timer operates the relay again on the set schedule. One thing the manual does not mention is that you can also adjust the seconds for each on/off time. To set seconds, when you are in program mode for any on/off sequence, just press the "manual button" to advance the seconds - it shows the seconds on the screen, in addition of course to day, hour, and minute. So for the router I use just one program set to on at 2:00:15 and off at 2:00:00 - therefore off for just 15 seconds at 2:00 AM. Really slick, love these!
Review: Great for use on 12v DC systems - I bought this to control a automatic chicken coup door I built, it does the job without breaking the bank. It has been running for about one week without any issues. The battery backup feature is great, the unit will not lose time or programming. The relay (contact) will not function on battery power, just for your information. I read some reviews before purchasing, some people had problems figuring out the wiring and programming. I had no issue with either on the unit I received, the terminals are clearly labeled on the back of the unit. Crimp-on spade terminals are needed for the wiring connections, there are no set screw seizures on this unit. The programming is really easy and intuitive, I only had to glance at the manual once. This unit has an automatic locking feature that cannot be disabled as far as I can tell, in order to make any programming changes you must first press the C/R button four times. This may be annoying for some, but I think it helps prevent inadvertent changes to your schedules/times and it only takes a second to unlock. There is a light on the front to indicate contact closure, a nice feature to know the relay is functioning at a glance.

## Questions & Answers

**Q: How do you get this to hold programming?  After reset/programming and sitting ~30s , it shows an "a" and doesn't work  (manual won't work).  Ideas?**
A: The  'a'  indicates that the timer is locked. The timer auto-locks after 30 seconds.  To unlock, you have to press the "C/R" key repeatedly (4-6 times, I think) in 10 seconds. The "a" will go away, and you can program start and stop times or operate manually

**Q: Can I use this to control a solar light for my chicken coop? If so, can you recommend a tutorial or specific parts I can buy?**
A: yes it works great for that, I used a solar panel from harbor freight on an old dolly with a used battery (made the entire unit mobile and a quick disconnect to the lights), I wired the solar panel to charge the battery then run wires from the battery to the timer which has been flawlessly working, I kept it all a 12 volt system, I bought 12 volt led lights and wired them to the other side of the timer, I had trouble setting the timer, but you can you tube it and its all there, this has kept my egg production up for sure and it cuts off long enough to give them a good nights sleep

**Q: What functions does the manual mode provide. can i push manual and have it close the switch for x minutes like my irrigation controller?**
A: Manual mode just lets you operate the switch in on or off mode untill you change the setting back to auto mode where the timer schedule takes over.

**Q: Will this single timer open and close a chicken coop door? I can only get the linear actuator to move in one direction. The a**
A: This is a timer that allows voltage to pass through. You need a control system like a plc to open and close a door.  Cheaper to walk out and do it.

### ⭐⭐⭐⭐⭐ rechargeable battery still works after five years
*by J***H on August 19, 2025*

I got one five years ago and it worked great for my purpose all summer. After not using for several years, it still works for a new project. I thought the backup battery would be dead; but it charged up and is working well enough so when I disconnect to move it, it keeps all my timer settings.
