I have this simple circuit (existing, not mine) that you toggle on and off with a simple push button and when you power it off and back on it stays off unless the button is pressed. I want to set this device on a timer but in doing so it never comes back on once the power has been cut. Is there a way to easily change the push button to a switch instead so if the power is killed it comes back on? Maybe another way to accomplish the same end goal?
I can't just hardwire the power as it's powering a PWM pump so I need to power up the circuit.
It's a kids toy, basically a little garden and the power turns on the light/pump.
