Hi
Can anyone help me in designing a automatic switching circuit which opens and closes in between 20ms and 500ms for 12v and 30A rating.

Hello,

What will be the repetition time for the 20 mSec to 500 mSec pulses?
You could take some very heavy Mosfets that are pulsed.

Initially the switch should be in open position after some time i,e 20ms switch should be closed and after 300ms it should be opened.I need to discharge the battery in different time intervals in the range 20ms to 500ms. What is the best switching timing circuit can be used.
