Movement effecting means causes relative movement of the movable contact between open and closed positions, and a closing spring assembly imparts movement to the movement effecting means to move the movable contact to the closed position. The closing spring assembly includes first and second members and a helical closing spring, with the first and second members extending into the central opening of the spring. Shock absorbing means is disposed within the spring opening to absorb energy released when the assembly is discharged.
