CPC:
Incandescent ignition; Igniters using electrically-produced heat, e.g. lighters for cigarettes (circuits therefor H01T15/00); Electrically-heated glowing plugs > structurally associated with fluid-fuel burners (lighters containing fuel F23Q2/00) > for gaseous fuel, e.g. in welding appliances > actuated by gas-controlling device
No child classifications to compare. This is a leaf node in both IPC and CPC.
