A switch is an optional parameter without (explicit) value (in fact it is a boolean). If left out when calling the function, it is $false, if you call with -NoInheritance it is $true.
You can call it with an explicit value, which you might want to do if the default value differs from $false, by e.g. using -NoInheritance:$false.

ok I kind of get it, if do dopermissions --NoInheritance it will:
switch (noinheritance)
{
Pattern 1 {Statement block}
Pattern 2 {Statement block}
Pattern n {Statement block}
}
is this correct?
switch (noinheritance)
{
Pattern 1 {Statement block}
Pattern 2 {Statement block}
Pattern n {Statement block}
}

No. [switch] and switch are totally different kind of things. $NoInheritance just has the values $false or $true, depending on what has been provided or left out at calling the function.
function DoPermissions
{
param( $permissionGroup, $folder, $level, [switch] $NoInheritance)
if (!$NoInheritance)
{
<# code to add inheritance #>
} else {
<# code without inheritance #>
}
}
# This are the same
DoPermissions -NoInheritance
DoPermissions -NoInheritance:$true
# This are the same, but reverse meaning to above
DoPermissions
DoPermissions -NoInheritance:$false
