Operation of the Contact Maker.—It will be noted in [Fig. 71] that the lifter is being pulled forward by the notched shaft. When pulled forward as far as the shaft will carry it ([Fig. 72]), the lifter is suddenly pulled back by the lifter spring. In returning, it strikes against the latch, throwing this against the contact spring and closes the contact for a brief instant. This movement is far too quick for the naked eye to follow ([Fig. 73]).
