Thanks, sir for the reply. I have used the spdt but I have no luck in connection since I can't make it connect to the current measurement. I have also used the link you provided, still no luck

Hi, You can use two breaker in place of a switch and provide it's external control. To charge the chapacitor one circuit breaker will be on by providing 1 logic and other will be off by providing logic zeros.
