Re: short or loose wire in light switch
Is there more than one switch that controls the kitchen light?
It's possible that it's only a loose wire at the switch or at the light fixture, it's also possible that the switch itself is bad. Turn off the circuit and tighten the connections at both the switch and the fixture, if that doesn't fix the problem then you'll need to replace the switch. ALWAY turn off the breaker feeding the circuit before working on the wiring. Be safe and live another day.
