A high voltage center break disconnect switch with two rotatable switch blades each operatively attached to a respective rotatable insulator for opening and closing the switch. A toggle locking drive assembly including a two-sided lever having three pivot points colinearly aligned thereon and two drive links each connected at one end thereof to one of the three pivot points. The two-sided lever connects at the third pivot point to a perpendicularly attached rotating shaft operatively connected to a drive pipe for opening and closing the switch. The drive links are each connected at the other end to a pivot point of a respective one of two levers each operatively mounted to one of the rotatable insulators. When the switch is in the closed position the five pivot points of the locking toggle drive assembly are aligned colinearly in a toggle lock position preventing the switch from unintended opening.
