2A is 2 amps 125vl = 125 volts 4a is 4 amps 250vac is 250 volts sounds like a power rating on the switch to me don't put more than 2 amps or "250 watts" of power draw on it if your running it at 125 volts and 4 amps or "500 watts" if your running it on 250 volts or the switch will overload

At 125 volts AC, the switch can open and close with a load of no more than 4 amps without failing. At 250 volts AC, the load can only be 2 amps. That means the maximium load for the switch is 500 watts. You figure it like this:
P (watts) = E (volts) x I (amps), so:
4 amps x 125 volts = 500 watts.
2 amps x 250 volts = 500 watts!
There ya go....

2A 125VL, =( 2 amps 125 volt alternating current of electricity,),,,,,,,, 4A 125VAC = (4 amps 125 volts of alternating current of electricity ),,,,,,,,,,,,, , 2A 250VAC = 2 amps 250 volts of alternating current of electricity) basicly it is the differance in the amount of AMPS & electrical current it needs too operate the fan ,,,

small numbers are the amps and the large number is the number of volts, that if you don't know what you are doing will end up knocking you on your A**
