You may be able to supply power from a nearby switch-it depends.
Some switches are installed in junction boxes with a hot and a nuetral. If your home is wired in this manner, you can, with some restrictions, connect to the switch wiring.
Other switches are installed in boxes with only hot wires. In this scenario, line power is supplied to the fixture junction box (ceiling outlet) and a 12/2 or 14/2 cable called a "switch leg" is run from the fixture box to the switch box. This is an efficient wiring method and is used frequently.
Electricians installing switch legs should clearly indicate that the white conductor is an energizine conductor (hot leg) by coloring a visible portion of the white insulation black with a marker or heat shrink tubing. Unfortunately, this practice is not enforced.
Some municipalities limit the number of light fixtures to 8 or 10 on a 15 amp circuit. I can't comment on your local codes.
Any time you are connecting a new cable, you CANNOT use a cable of lesser amperage. It doesn't matter if the sconce is limited to 60 watts and thus only draws 1/2 amp. All hardwiring in a circuit must be matched to thte fuse/circuit breaker. If your existing switch is wired with 12 ga cable, you cannot legally extend the circuit with 14 ga.
