Patent ID: 7504916

Claim:
A solenoid switch comprising: a pair of fixed contacts spaced away from each other; a solenoid; a contact pressure applier; and a moving contact configured to be moved by the solenoid to strike the fixed contacts and keep contact with the fixed contacts under pressure applied by the contact pressure applier, thereby bridging the fixed contacts, the moving contact being also configured to have, when striking the fixed contacts, a flexural rigidity lower than or equal to 1000 N/mm, thereby preventing contact bounce from occurring in the solenoid switch, wherein the solenoid includes: an iron core; a field winding wound around the iron core to form an electromagnet; a plunger disposed to have a gap with the iron core, the plunger being configured to be moved by magnetic attraction of the electromagnet when the field winding is energized; and a shaft fixed to the plunger and configured to transmit the movement of the plunger to the moving contact, thereby causing the moving contact to strike the fixed contacts, and wherein the moving contact has an outer edge protruding from a most outer part of each of the fixed contacts in a radial direction of the solenoid switch, and is configured to strike and keep contact with the most outer part of each of the fixed contacts.
