I need a timer that will complete a circuit when sent a signal and then shut off after 30 seconds or so.

• It can be no larger than 1/2" diameter and 1" long.
• It doesn't need to be programmable or adjustable.
• It will use DC voltage -- probably 3V.

I know these are available, but I just can't find them when I search. Maybe they're called something else. (I'm not well versed in electronics.)

Thanks!

 

What kind of circuit is it switching?
Inductive? Restive? power reqd?
Max.

I'm going to make a new post for the entire project, since I don't know what I'm doing. lol!

You can get a tiny COB module to do your job: C005
