Full Title

Full titles differ between systems:

IPC:

Electronic switching or gating, i.e. not by contact-making and -breaking > characterised by the way in which the control signals are generated > Proximity switches

CPC:

Electronic switching or gating, i.e. not by contact-making and –breaking (gated amplifiers H03F3/72; switching arrangements for exchange systems using static devices H04Q3/52) > characterised by the way in which the control signals are generated > Proximity switches (H03K17/96 takes precedence)

Of 3 combined children, 2 exist in both systems.

1 codes are CPC-only extensions.

Note: 1 CPC extensions are marked as secondary classification only.
