I found this schematic online and figured it would work perfect for my application. I am running a circuit with a 9V and after a set amount of time the circuit and current load on the battery will be disconnected. I breadboarded this circuit exactly as shown, but the load would never disconnect. It was on as soon as the 9V was connected without pressing S1. Did I do something wrong. According to what I read it should work as follows.
S1 is closed; circuit powers up and supplies power to load.
S1 is open: 555 starts timing based on RC combo
At the end of the delay power to load and battery is removed.
Any info would be appreciated.
