Solenoids vs actuators

I have never used actuators for shaved handles and similar functions, my question is do they reset after the power is cut, or do they require (I think they do) a mechanical reset.

Thanks

Hi! they should reset by itself .

I am using them to pop custom toolbox doors, so the weight is much lighter, but I need them to reset themselves.  I might just use remote trunck pop kits for economics.  Need to do a test to see if the 15lb is strong enough.

Thanks guys
