DEFINITION

Classification: 335/185

(under subclass 2) Subject matter wherein the significant structure comprises apparatus in addition to, but actuated by, an armature or armatures whereby at least one movable contact is caused to be actuated from a first position to a second position in relation to a fixed contact resulting in an electrical circuit being completed or broken.

(1) Note. For devices in which the movable contact is pivotably connected upon or relatively movably attached to the armature the search is in subclass 200.

(2) Note. When the specific contact actuating structure is shown or disclosed in a device falling in a specific type classifiable elsewhere in the class, and the claims do not

recite elements of the more comprehensive structure; search must be extended to the more specific subclass.

SEE OR SEARCH THIS CLASS, SUBCLASS:

71+, for motor operated switches with contact actuating structure.

93+, for periodic switches with vibratory reed or other periodic contact actuator. 121+, for multiple contact switches with significant contact actuating means.

154, for vacuum or hermetically sealed type switches with particular contact actuating means.
