I have this delay circuit. I am trying to delay the power to R1(which will be an android phone) by 1 second. SW10 is my SPST relay. Can i replace the relay with something cheaper and physically smaller without losing significant voltage across it as the phone requires 5V and 500mA.
Darlington pair but could not make it work due to their high voltage drop as well.
Enhancement N-fet might be a solution? but I am just not able to figure it out. If someone can draw me a circuit, I would be high grateful.
