ABSTRACT:
In the switch, a terminal section and a contact section of a fixed contact are separately formed and the two sections are connected via a coil made of a conductive metal wire. After electrical connection is established between a movable contact and fixed contacts, a weak current with no arc discharge flows between the movable and the fixed contacts. This prevents build-up of oxide or carbide on the contact surface, allowing the switch to have stable contact operation and accordingly reliable electrical connection.
