Lead-out arrangement for an electromagnetic switch

Abstract

A lead-out arrangement for an electromagnetic switch is disclosed which is capable of substantially preventing injury or damage to the covering film or insulating layer on the lead-out end of an exciting coil without enlarging the size of the electromagnetic switch. The electromagnetic switch includes a bobbin having a cylindrical portion and a pair of flanges formed at the opposite ends of the cylindrical portion, an iron core inserted into the bobbin from its one end and having an end wall in intimate contact with the outer peripheral surface of one of the bobbin flanges at the opposed end of the bobbin, and an exciting coil wound around the bobbin. A notch is formed in the iron core end wall and a projected guide wall extends outwardly from the one bobbin flange through and along the notch, the thickness of the iron core end wall being reduced at a portion thereof adjacent the notch. The projected guide wall is connected with the one bobbin flange through a connecting portion which is intimately secured to and extends along the thickness-reduced portion of the iron core end wall so as to smoothly guide the lead-out end of the exciting coil at a relatively large radius of curvature.
