The Startix automatic engine starting mechanism was a relay in a small box added to the vehicle's electrical system. It automatically started an engine from cold or if stalled. It was supplied to vehicle manufacturers in the mid 1930s and later as an aftermarket accessory — in the USA by Bendix Aviation Corporation[1] Eclipse Machine Division and in UK by Joseph Lucas & Son both of which businesses made electric self-starters. Such devices are now part of the engine management systems which switch off and on to conserve fuel.
