If there were a bunch of neutrals in the same box as the switch box they might have loosened-but the most likely cause is a trip GFI, which should not have happened if the power was off when you changed the switch--make sure there is nothing plugged into any outlet
exercise the circuit breaker-force it all the way off, it should cock , then push it to the on position--then check the GFI's for a green light if no light put the reset buttons
