Claims

[Scope of utility model registration request]

Sliding type movable contacts and fixed contacts that open/close or open/open in synchronization with the opening/closing of the main contact of a switching device, mechanically holding the movable contact and adjusting the synchronization with the main contact within a specified time. A contact support made of an insulator with a gear-shaped hole in the center to allow for control, and a control shaft with a gear-shaped cross section that fits into the gear-shaped hole of the contact support and rotates the movable contact. Auxiliary switch.
