Mega-tsunami for New York will be 400 meters; then engulfed-in-lava Los Angeles will be flooded too; also, asteroid destroys Gulf of Mexico; only Alaska, Eurasia, and Africa remain (obviously without coasts). 1st big earthquake in Russia; 2nd bigger one in China (will be split in half; radiation!); 3rd biggest will be in the USA (Greek Orthodox monk Elidiy from Africa); forgive me.

WHICH 220 volt appliances??

What is a 110 volt switch??

Unless you say something sensible, the answer must be NO.

240vac devices typically use split-phase power (a pair of 120vac lines 180° out-of-phase), and a 240vac motor almost always requires split-phase.

With a 240 volt electric stove, for example, the high-power oven elements won't work at all with a single 120vac line, nor will the large stovetop elements.  Depending on the stove wiring, one or the other small elements might work, but likely not both.  It's quite possible that only the clock and some lights will function.

A motor or heating element, intended for 240vac but that happens to work with 120vac, will generate one-quarter of the power that was intended.

If you're asking whether a standard on-off switch can be used to toggle a 240 volt connection, the answer is an almost certain NO.  This is because the standard single-pole switch can only disconnect a single hot wire, and 240 volts generally use TWO hot wires, both of which must be disconnected or connected simultaneously with a double-pole switch.  See https://www.leviton.com/sites/REST/controller/LCPr... for a typical example.

Consequently power is reduced to ½×½=¼.  Taking only voltage and load under consideration, this is expressed by the equation W=V²/R, in which W is power in watts, V is voltage, and R is load resistance in ohms.

but then out put will be less

No.

Logic alone should tell you that a 50% reduction in voltage

will seriously affect the operation of any appliance.

Likewise, going the other way would cause damage.

And --- a switch is not a source of power;

it is a method of controlling power.
