class SWPowerInterface():
    """ This is the interface class for the Switched Power ports on Extron devices (extronlib.device). The user can instantiate the class directly or create a subclass to add, remove, or alter behavior for different types of devices.

    Arguments:
     Host (extronlib.device) - handle to Extron device class that instantiated this interface class
     Port (string) - port name (e.g. 'SPI1')
    
    Parameters:
    Host - Returns (extronlib.device) - handle to Extron device class that instantiated this interface class
    Port - Returns (string) - port name
    State - Returns (string) - current state of IO port ('On', 'Off')
    
    Events:
    Offline - (Event) Triggers when port goes offline. The callback takes two arguments. The first one is the extronlib.interface instance triggering the event and the second one is a string ('Offline').
