No, you do not have to remove a cover to "get at it", you operate the switch qithout removing a cover. Just like this switch:

As you can see, this is also an external switch. You flip it when it is mounted on something. But in order to replace it, you can't just use a hammer and knock it off, you have to open the device it is located in and remove the internal part of the switch.

All external switches connect to internal components, but that doesn't mean that switch is an internal switch.
