The arc extinguishing chamber housing is provided with permanent magnets to extinguish an arc generated at an opening time when the movable contact separates from the fixed contacts from a state in the closed position wherein the movable contact is contacting with the fixed contacts. In a state wherein the movable plunger is in the opened position, a magnetic circuit is formed starting from the permanent magnets and returning to the permanent magnets through the movable plunger.

  • Patent number: 8754556
    Abstract: In a starter for starting an on-vehicle engine, a solenoid is provided to push a pinion gear. The solenoid has an electromagnetic coil composed of a single coil and electrically separated from a motor circuit, a fixed core, and a plunger. Supply of excitation current to the electromagnetic coil allows the fixed core to be magnetized to attract the plunger. Hence, a movement of the plunger results in a push of the movable member toward the ring gear. A switch is provided in the circuit and has a contact, a movable core, and a switch coil functioning as an electromagnet attracting the movable core in response to supply of current to the switch coil. A movement of the movable core results in on/off switching operations of the switch. The switch is allowed to operate independently of the solenoid when both the switch and solenoid are controlled.
