(ɪɡˈnaɪtrɒn; ˈɪɡnɪˌtrɒn)
n
(Electronics) a mercury-arc rectifier controlled by a subsidiary electrode, the igniter, partially immersed in a mercury cathode. A current passed between igniter and cathode forms a hot spot sufficient to strike an arc between cathode and anode
[C20: from igniter + electron]
