Answer for USA, Canada and countries running a 60 Hz supply service.A properly wired 240 volt appliance has 4 wires. One wire is L1 power. The other wire is L2 power. The third wire is considered neutral, and the 4th wire is utilized as a safety ground wire. Either L1 or L2 to neutral is 120 volts. L1 to L2 is 220 volts.

Generally Black is considered L1. Red is considered L2. White is considered Neutral and Green is Ground.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

Power out of a switch is not negative. It is still the "hot" conductor. The ground wire in a switch junction box in home wiring is the bare wire. It is nearly impossible to mix these two wires up. Most likely if the "hot" supply comes into the switch box the neutral wire will be with it. Just wire nut the two white wires together, incoming and outgoing. The two black wires will be connected to the switch to operate the light fixture.
