Abstract

Provided in the present solution is a multi-switch interlocking apparatus, related to the technical field of power supply and power distribution apparatus, comprising a first rotating rod used for controlling the opening or closing of an end switch, a second rotating rod used for controlling the opening or closing of another end switch, a first connecting rod mechanism rotatably connected to the first rotating rod and used for locking the second rotating rod, and a second connecting rod mechanism rotatably connected to the second rotating rod and used for locking the first rotating rod. The multi-switch interlocking apparatus of the present solution implements multiple switch interlocking modifications and adjustments, implements the goal of other switches being locked and prevented from being opened when one switch is opened, thus preventing a short circuit accident from be caused by an inadvertent operation of opening other switches when a switch is opened. The structure is compact and simple to install and operate; moreover, by using a mechanical interlocking scheme, the remaining switches are locked when one switch is opened, safeness and stability are improved.
