Abstract
A switch interlock apparatus for use with switch panels that have pairs of functionally related switches, in which the handles for the switches are mounted in tandem and aligned with their pivot axes parallel to and spaced apart from one another, in which one of the switches must be flipped, before the other switch can be flipped. The switch interlock apparatus mechanically connects the handles of two functionally related switches so that as one switch moves from an “OFF” to an “ON” position, the interlock constrains the handle of the related paired switch to move from “ON” to “OFF” first. In a preferred embodiment, the switch interlock apparatus incorporates a monolithically formed interlock member that can be directly mounted to a switch panel without intermediate assembly steps.
