I have two single pole switches in one box. One is a single pole dvcl-153p controlling a set of LED ceiling lights and everything works fine. The second is a single pole standard (non dimmable) toggle switch controlling a "florescent style" light that was converted to use LED bulbs. Both lights share a common power source line into the switch box, but the two lights are on separate switched circuits.
The second light switch also work fine, but only when the dvcl-153p dimmer switch is in the off position. When the dvcl-153p dimmer is in the on position, the LED lights connected to the standard switch stop working. Based on an electrical tester they are still getting power, but they go out. Why would a single pole dvcl-153p dimmer switch impact an LED light that is connected to a different (non dimmable) single pole switch?
