Short circuit in electrical wiring if you have several light switches or light fixtures that are not working then there may be a short in the electrical wiring or most likely a loose connection has developed.

Wall light switch short circuit.

This circuit is wired with a 2 wire cable running from the light to the switch location. There should be power at the light switch verify with the meter or non contact tester if power is there turn off the breaker and verify power is off now replace the switch wire for wire if it is a standard 2 wire switch just move the wires over in this case black white don t later but if it has a bare copper wiry that goes on the green screw on the new switch. This will prevent the switch from working properly and could also be a fire risk. The neutral from the source is connected directly to the neutral terminal on the light and the source hot is spliced with the white loop wire.
