I have tested this and it works fine ! This will do what you want to achieve.

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")
if((Get-PSSnapin | Where {$_.Name -eq "Microsoft.SharePoint.PowerShell"}) -eq$null) {
 Add-PSSnapin Microsoft.SharePoint.PowerShell;
}

$SiteList = @("Department","Contact")
foreach($site in $SiteList){
New-SPWeb –url http://Demo/$site -name "$site" -Template STS#0 –AddToTopNav –UniquePermissions –UseParentTopNav

if($site -eq "Department"){
    $Departments = @("IT support","Financial","HR")

    foreach($Department in $Departments){
    New-SPWeb –url http://Demo/$site/$Department -name "$Department" -Template STS#0 –AddToTopNav –UniquePermissions –UseParentTopNav

    }
}

elseif($site -eq "Contact"){
    $Contacts = @("Contact1","Contact2","Contact3")

    foreach($contact in $Contacts){
    New-SPWeb –url http://Demo/$site/$contact -name "$contact" -Template STS#0 –AddToTopNav –UniquePermissions –UseParentTopNav
    }
}    
}
