H01H 13/702

with contacts carried by or formed from layers in a multilayer structure, e.g. membrane switches

Introduced: January 2000

Full Title

Full titles differ between systems:

IPC:

Switches having rectilinearly-movable operating part or parts adapted for pushing or pulling in one direction only, e.g. push-button switch > having a plurality of operating members associated with different sets of contacts, e.g. keyboard > with contacts carried by or formed from layers in a multilayer structure, e.g. membrane switches

CPC:

Switches having rectilinearly-movable operating part or parts adapted for pushing or pulling in one direction only, e.g. push-button switch (wherein the operating part is flexible H01H17/00) > having a plurality of operating members associated with different sets of contacts, e.g. keyboard (mounting together a plurality of independent switches H02B) > with contacts carried by or formed from layers in a multilayer structure, e.g. membrane switches

Of 6 combined children, 3 exist in both systems.

3 codes exist only in IPC.
