of circuit-makers or -breakers, or pick-up devices adapted to sense particular points of the timing cycle

Introduced: September 1968

Full Title

Full titles differ between systems:

IPC:

Arrangement of distributors, circuit-makers, circuit-breakers or pick-up devices for electric spark ignition > of circuit-makers or -breakers, or pick-up devices adapted to sense particular points of the timing cycle

CPC:

Arrangements of distributors, circuit-makers or -breakers, or pick-up devices (advancing or retarding ignition or control therefor F02P5/00; such devices per se, see the relevant classes of Section H, e.g. rotary switches H01H19/00, contact-breakers, distributors H01R39/00, generators H02K) > of circuit-makers or -breakers, or pick-up devices adapted to sense particular points of the timing cycle

Of 6 combined children, 5 exist in both systems.

1 codes are CPC-only extensions.
