It sounds like the router is in the fully plunged position with the spindle lock engaged. This causes the clear power switch door to lock in the closed position so the router can't accidentally be turned on and cause damage to the router. un-plunging the router enough to disengage the spindle lock will allow the door to open and the router to be turned on. This same mechanism will prevent the spindle lock from engaging when the power switch is in the on position, so you don't have to worry about over plunging the router in use.
