Abstract
An electromagnetic switch device includes: a fixed iron core; a plunger configured to move between a contact position and a separation position; a suction coil configured to generate, with a current supplied thereto, a magnetic field configured to move the plunger from the separation position toward the contact position; and a holding coil configured to generating, with a current supplied, a magnetic field configured to move the plunger from the separation position toward the contact position and a magnetic field configured to keep the plunger in the contact position. The holding coil is arranged in such a manner as to deviate, in a moving direction of the plunger, with respect to a contact surface of the fixed iron core.
Claims12
An electromagnetic switch device, comprising:
- a fixed iron core;
- a plunger configured to move between a contact position and a separation position, the contact position being a position for allowing the plunger to be in contact with the fixed iron core, the separation position being a position for allowing the plunger to be apart from the fixed iron core;
- a suction coil configured to generate, with a current supplied thereto, a magnetic field configured to move the plunger from the separation position toward the contact position;
- and
- a holding coil configured to generate, with a current supplied thereto, a magnetic field configured to move the plunger from the separation position toward the contact position and a magnetic field configured to keep the plunger in the contact position,
- wherein the holding coil is arranged in such a manner as to deviate, in a moving direction of the plunger, with respect to a contact surface of the fixed iron core with which the plunger comes into contact.
