Electromagnetic switching device for starter utilized to start engine of automobile, has cases structured in body such that magnetic fluxes are formed in flange portion of core in opposite directions when coils are charged, respectively

摘要

The device has an electromagnetic relay (6) and an electromagnet (9) including switching cases that constitute outer frames serving as magnetic circuits for the electromagnetic relay and the electromagnet, respectively. The switching cases are fixed in a body such that two magnetic fluxes are formed in a flange portion of a fixed core of the electromagnet in opposite directions when two excitation coils (12, 20) of the electromagnet and the electromagnetic relay are charged, respectively.
