(under the class definition) Subject matter including at least one contact actuating means of the type classifiable in this class in combination with a diverse type actuating means of a type classifiable elsewhere in another art class and each one acting singly or conjointly to control the same single set of switch contacts. The two or more actuating means may be physically located in the same housing or casing and may have cooperative features as long as each one is operative independent of the other. Some examples of diverse type switch actuating means are the mechanical special application switches in Class 200.
(1) Note. For similar subject matter including the combination of electromagnetic or magnetic control means combined with thermal-current responsive means, search will be in Class 335, Electricity: Magnetically Operated Switches, Magnets, and Electromagnets, subclasses 141+ and in the classes and subclasses referred to in the search notes under
the subclass definition.
SEE OR SEARCH THIS CLASS, SUBCLASS:
54, and 90, for electrothermally actuated bimetallic switches which operate with a snap action and have additional magnetic flux sources to act as holding or biasing means.
