I need to toggle 4-lines from off to on around once an hour, 5vdc and about 1A max. The Off or On state will be held for a preset time (20+ minutes) via one Data pin per channel on a UNO. Essentially a square wave output but with UNO controlled mark/space.
I found the switch in the pic at Mouser and am thinking that maybe using a servo to hold it down then release as needed, but that seems pretty cumbersome. Maybe even remove the spring and just move it up and down.
I have searched but not finding anything. I am sure they exist, but I am just not sure what search terms to use, so thought I’d ask the collective knowledge, here is there is a better way.
