DIFF Subgroup
H03K 17/292

in thyristor, unijunction transistor or programmable unijunction transistor switches

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Electronic switching or gating, i.e. not by contact-making and -breaking > Modifications for introducing a time delay before switching > in thyristor, unijunction transistor or programmable unijunction transistor 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) > Modifications for introducing a time delay before switching (modifications to provide a choice of time-intervals for executing more than one switching action H03K17/296) > in thyristor, unijunction transistor or programmable unijunction transistor switches

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