Could a transistor,FET, or SCR be substituted for the relay, or is there a way to make a solid state circuit such as this that would cut out around 3.0 volts? I need something to disconnect a 1watt LED light circuit from a battery pack when the voltage drops to 3 volts or so. Any help would be appreciated.Jefhttps://www.blogger.com/profile/15613440714606981760noreply@blogger.com
