Abstract:
A starter magnet switch, comprising:a fixed iron core;a movable iron core which is allowed to reciprocate in a direction in which said movable iron core is brought in or out of contact with said fixed iron core;an opening spring which urges said movable iron core in a direction where said movable iron core is dissociated from said fixed iron core;a coil which moves said movable iron core by excitation in a direction where said movable iron core is brought in contact with said fixed iron core against said opening spring;a rod which includes an annular mounting groove defined in an outer periphery of a leading portion thereof and reciprocates together with said movable iron core;a plurality of fixed contacts disposed at given intervals;a movable contact which is supported by said rod in a state where said movable contact can reciprocate in an axial direction of said rod, which is brought in or out of contact with said fixed contacts by the reciprocation of said rod, and which electrically connects/disconnects said fixed contacts;a contact spring which is disposed between said rod and said movable contact and urges said movable contact toward said fixed contacts;a stopper which includes a pair of semicircular pieces which are semi-annular and mounted on said mounting grooves so as to surround said rod in a state where said semicircular pieces are opposed to each other, and which regulates the movement of said movable contact in the axial direction of said rod; anda cover which includes a ring portion disposed between said movable contact and said stopper and a cylindrical cover body that surrounds said stopper, and which prevents said stopper from being disengaged from said rod.
