Abstract of the Disclosure A disconnect switch has a fixed tubular contact and a tubular contact movable into connection with the fixed contact. A movable auxiliary contact within the movable tubular contact can travel into connection with a stationary auxiliary contact on the fixed tubular contact. The switch has short pre- breakdown times at higher voltages and includes a support shaft carried by the movable tubular contact and at least one sleeve which is arranged on the shaft. A pantograph-like connecting member has one end fastened to the sleeve and the other end coupled to the movable auxiliary contact. Elements of a mechanical control device are also fastened to the outside of the sleeve and, in cooperation with fixed extrusions of the outer switchhousing, cause the sleeve to rotate when the movable tubular contact is moved.
