Abstract
A transfer switch for switching between power sources for a load includes a plurality of symmetrical phase plates, a plurality of stationary contact pads associated with each said phase plate, each stationary contact pad associated with a power source, a movable contact assembly associated with each phase plate, and a shaft connecting the phase plates and upon which each movable contact assembly is mounted for movement between stationary contact pads associated with each phase plate. The above transfer switch allows for two, three and four-pole modular configuration with minimal additional hardware.
