How to call a script with an argument in powershell?

Question

PowerShell

Good day!
Wrote a bash script

start) {
бла-бла
}
stop) {
бла-бла
}
restart) {
бла-бла
}
case "$1" in
 
   start)
       start
       ;;
   stop)
       stop
       ;;
   restart)
      restart
       ;;
    *)

how to do the same in powershell? so that when a script is called with the stop\start\restart key, a certain piece of code is executed?

        Write-Host 'start'
    }
    'stop' {
        Write-Host 'stop'
    }
    'restart' {

    }
}

You can use the $args variable
