Abstract
A valley section is provided between a high-voltage arc contact and a high-voltage main contact. Because of the presence of the valley section, resistance between contacts is reduced while a moving arc contact makes contact with the high-voltage arc contact and then slides up to making contact with the high-voltage main contact.
