Full Title
Full titles differ between systems:
IPC:
Mechanisms for operating contacts > Operating parts, i.e. for operating driving mechanism by a mechanical force external to the switch
CPC:
Mechanisms for operating contacts ( thermal actuating or release means H01H37/02) > Operating parts, i.e. for operating driving mechanism by a mechanical force external to the switch
CPC subdivides this area 3x more granularly than IPC with 10 additional codes.
10 codes are CPC-only extensions.
