In this arrangement the source for the circuit is at the light fixture. 3-wire cable runs from the switches on each side, to the light. The hot source is spliced to the common terminal on SW2 and the hot terminal on the light fixture connects to the common terminal on SW1. The traveler wires are spliced at the fixture box and run to the traveler terminals on both switches.
This arrangement makes it possible to power the heating elements in the appliance using the two 120 volts combined and one 120 volt wire to power timers and lights.
