ABSTRACT:
An electromagnetic switch is provided which is equipped with a built-in electronic control circuit working to control energization of an exciting coil. The electronic control circuit is disposed within a chamber defined by a magnetic plate to be separate from a contact chamber. In other words, the electronic control circuit is disposed between the magnetic plate and the exciting coil, thereby avoiding the adhesion of conductive dusts, as arising from the wear of contacts, to the surface of the electronic control circuit. This results in decreases in electric insulation and short-circuit of the electronic control circuit and also eliminates the need for additional special parts to electrically insulate and shield the electronic control circuit, thus permitting the electromagnetic switch to be reduced in size and produced at a decreased const.
