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 spacers between contact carrying layers

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 spacers between contact carrying layers

No child classifications to compare. This is a leaf node in both IPC and CPC.
