Ok with 1 rpm activated switch onto lets say a door lock selenoid that someone .... ( i honestly forgot the screen name no offence) recommended. The rpm activated switch would only open it and not close it am i not correct???? so that means you would need 2 rpm activated switches 1 to open and 1 close it, or just a manual switch to close it???? anybody have any feed abck on this like a selenid that wouldnt need 2 switches ??? or am i totally out to lunch ???
thanks

That made about as much sense as a buy-1-for-the-price-of-2-get-1--free sale...
