Abstract
A switching device changes over breaking and closing of an electric current by opening/closing a contact portion. An electrically-operated motor generates energy for closing a contact and energy generated by the rotation of the electrically-operated motor is accumulated in a breaking spring. The energy generated by the electrically-operated motor is transmitted to the contact by way of a cam, a breaking spring link, a transfer lever and the like. The breaking spring is arranged in the midst of the converting lever. When the contact is opened, the electrically-operated motor is stopped and the energy accumulated in the breaking spring is released.
