characterised by the mechanism between keys and layered keyboards

Introduced: January 2006

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 > characterised by construction, mounting or arrangement of operating parts, e.g. push-buttons or keys > characterised by the mechanism between keys and layered keyboards

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 > characterised by construction, mounting or arrangement of operating parts, e.g. push-buttons or keys > characterised by the mechanism between keys and layered keyboards

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

IPC defines codes here since 2006.
