Class Information
Number: 116
Name: Signals and indicators >
Description: (A) This class is limited to mechanical, as distinguished from electrical, devices for giving signals of the nature of either alarms or indicators, which signals are generally due to some movement of some part or element from a normal or nonsignaling or signal-controlling position. The signal may be of any type which appeals to any one or more of the senses, but is generally a bell, horn, whistle, semaphore, light-shutter, explosive device, pointer, or flag. Methods are classified in the appropriate subclasses with the signal devices unless specifically provided for by a method subclass.
