Introduced: January 1980

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 > Switches controlled by moving an element forming part of the switch > using a magnetic movable element

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 > Switches controlled by moving an element forming part of the switch > using a magnetic movable element

CPC subdivides this area 3x more granularly than IPC with 2 additional codes.

2 codes are CPC-only extensions.

Note: 2 CPC extensions are marked as secondary classification only.

IPC defines codes here since 1985.
