Query: Light Switch

I have had nothing but problems with this since I bought it.I installed it as shown in the instruction and it did not work.after rereading the insturction and reinstalling it it still did not workI took it to my shop and was testing it when I noticed a very very small switch that turned the unit off and on. There was no mention of this switch in the instruction at all. Of course it came turned off.I reinstalled the switch and it worked great except with flousant lights they flicker very fast so could not use the floursant light bulbs. Also the unit when on interfers with every radio in the house. It is now not working again and not sure why. This only worked for 2 weeks.
