摘要： The starter-use electromagnetic switch has an electrical contact interposed in a power supply line for supplying power from a battery to a starter motor, the main contact being turned on and off in interlock with energization of an electromagnet implemented by an excitation coil. The electromagnetic switch includes a connection fitting connected to the excitation coil at one end thereof and drawn outside through a resin cover of the electromagnetic switch at the other end thereof, and a terminal fitting electrically and mechanically connected to the other end of the connection fitting at one end thereof, the other end of the terminal fitting being branched into first and second terminal pieces. The first terminal piece serves as an excitation terminal supplied with power from the battery. The second terminal piece serves as a connection terminal connected to an excitation terminal of an external electromagnetic switch through a cable.

摘要： An electromagnetic switch operative to close and open an electrical contact arrangement to thereby turn on and off an electrical current flowing through an electrical circuit. A movable iron core includes a shaft insertion hole that extends in an axial direction of the movable iron core and has an opening in an end face of the movable iron core axially opposing a movable contact of the electrical contact arrangement. The hole includes a step disposed at a position along the depth, a shaft fixture section on a bottom side of the step, and a shaft guide section on an opening side of the step. An inside diameter of the shaft fixture section is smaller than an inside diameter of the shaft guide section. One axial end side portion of the shaft is press fit in the shaft fixture section.

摘要： In an electromagnetic switch, a magnetic plate, which forms a part of a magnetic circuit, and a bobbin of a second coil are assembled as one body by insert molding. An outer circumferential surface of the magnetic plate is adhered to an inner circumferential surface of a cylindrical frame made of metal. Because a large amount of heat energy generated in the second coil is transmitted to the magnetic plate, this can discharge the heat energy through the magnetic plate to the cylindrical flame. Because a mounting surface of the cylindrical frame is fixed to an end part of a starter housing case, it is possible to easily discharge the heat energy generated in the second coil through the cylindrical frame to the starter housing case. This structure prevents a temperature rise of the second coil and contributes entire-size reduction of the electromagnetic switch.

摘要： There is disclosed a switching apparatus for a starter comprising a resistor for suppressing a startup current of a motor when an engine is started, an electromagnetic relay for bypassing the resistor to energize the motor after the motor is started, a function for pushing a pinion of the starter toward a ring gear, an electromagnetic switch for opening and closing a main contact of the motor circuit. The resistor, the electromagnetic relay, and the electromagnetic switch are integrally accommodated inside a housing formed of a metallic bottomed frame and a contact cover, and are connected to the motor circuit via two external connection terminals fixed to the contact cover. The apparatus can facilitate connectivity to the vehicle side by reducing the number of cables and can enhance an installation property.

摘要： The electromagnetic switch includes an excitation coil serving as an electromagnet when energized, a fixed core magnetized by the electromagnet, a movable core configured to move by being attracted by the fixed core being magnetized, a pair of fixed contacts interposed in an electrical circuit, and a movable contact configured to move in accordance with movement of the movable core to make and break electrical connection between the fixed contacts. The electromagnetic switch further includes a stopper for restraining movement of the movable core for preventing short-circuit between the fixed contacts through the movable core due to abrasion of members of the electromagnetic switch.
