This assembly is designed as a unitary input three-phase electric power switch having provisions for connecting the phase of the power to a standard rotation if it does not already exist as such. A three-pole on-off switch is followed by a three-pole double-pole relay sub-assembly having differential resistance-capacitance phase-determining and relay-energizing circuits.
