A disconnect switch is disclosed which may be mounted in a vertical or underhung position and operated from below. The disconnect switch includes a switch blade having a pivoting end and a laterally extending lever arm at the pivoting end. A toggle linkage operating mechanism is positioned opposite the lever arm in a direction away from the switch blade. When the disconnect switch is positioned vertically, the toggle linkage will be below the switch blade. The toggle linkage is connected between the lever arm and a fixed terminal pad and has an operating arm integral with the toggle link connected to the lever arm and extending away from the toggle linkage. The operating arm is rotatable by a hook stick about the knee of the toggle linkage and about the lever arm to pivot the switch blade between a closed and open position with a fixed contact.
