DEFINITION

Classification: 200/502

Solid contact:

(under the class definition) Subject matter wherein an electrical circuit si completed by the physical engagement and disengagement of two solid conductive elements (i.e., contacts) to form a complete switch.

(1) Note. Included in this subclass are devices which may have plural sets of contacts, however, the plurality herein

is an obvious duplication of a single contact.

1+, for devices arranged to control two or more circuits.
