Newly installed LED bulbs will not turn off by using the switch. I have six lights in my kitchen ceiling controlled by a single pole on off switch, no dimmer. Replaced those incandescent bulbs with LED bulbs. The LED bulbs stay on regardless of the switch position. I pulled the wires from the switch and the LED bulbs still stay on. They are full on, not just Dimming. I removed one of the LED bulbs and put back in an incandescent bulb, reconnected the switch and it works fine. As long as I have that 40 W incandescent bulb in place everything works. It will not shut off when I use all LED bulbs. I actually have to turn off the breaker to get the lights off. They stay off until I flip the switch on again and then they will not turn off.
