Why does Lutron motion sensor light switch have low amp?
2 amp is really small for a 120V switch type replacement. The ones I use for a single fixture are rated at 6.Amps. you might want one that is larger switch this is 800W a little bigger. With that said the total draw needs to be less than the rated value to use them. I usually like to use 50-75% of the rated value so they will last longer. Power in watts / Volts = Amps, add up the wattage total you will be switching and that will give the minimum size of the switch to use.
