Abstract
An interlocking base for use with stacked interlocking electronic assemblies which increases the mechanical stability of the base-stack combination. The increased stability allows a stack of up to four electronics assemblies to be subjected to an inclination of 15 degrees from the vertical in any direction without falling over. The base is furnished with an AC power cord and an ON/OFF AC power switch to provide single switch control of the ACs power conducted to the electronic assemblies of the stack. Single switch control saves operator time and motion, and also prevents accidentally leaving one of the assemblies of the stack ON while turning all the others OFF at the completion of work.
