I 'm hoping everyone can point me in the right direction

I'm hoping everyone can point me in the right direction ... I'm not sure if this is the item I'm looking for or there is something better but this is what I'm trying to do.

 

I need some type of off delay switch that stays on for a programmed amount of time and then turns off unless the switch/button is pressed again. I want it to power a 12v DC device for 60 seconds (or a programmable time) and then turn completely off till the button is pressed again. If the button is pressed during the 60 seconds the clock would restart and it would stay on for 60 seconds. I've found this device "Mini Timer Time Delay Relay" https://www.amazon.com/gp/product/B01HNDOCKK/ref=ox_sc_act_title_5?smid=A1YGHK4VRDPUC4&psc=1

 

I think this could work. My ultimate goal is for this not to use any power unless the button has been pressed and for that only to last 60 seconds unless the button is pressed again. Would this work? Would you recommend something else?

From the data sheet, "Circuit consumes 4ma during power off state". If you are using 10A for 60 seconds that is about the same power draw as .004A for 42 minutes. (10/0.004/60)

I don't know who makes an auto-off time delay twin coil latching relay.

 

If you wanted to roll your own this Omron relay would be a good choice.

FYI - the data sheet link at Mouser is wrong, the correct data sheet is at omronfs.omron.com - omronfs.omron.com/en_US/ecb/products/pdf/en-g5rl_uk.pdf

 

You'd have the push button apply power to the set coil and the relay contact would apply power to a 555 timer circuit and the load. The timer would count 60 seconds then activate the reset coil cutting all power use.

Wow, I would just have programed it up on an arduino but this looks elegant. I wish I was an EE sometimes instead off a CS guy. I guess the only benefit of the arduio is you could adjust the timer with code.
