With the earth end as we know it? Will it cause a nationwide blackout??
Seriously... Is there a major safety issue? I DO NOT intend to dim anything, just use the switch. Is it an issue of the switch not lasting as long or what?
Possibly. To buttress what Brian said; In the shop light situation, it is the magnetic ballist that does not like being fed by the triac in the WS467. Even when not dimmed, the waveform is distorted (yes even with 100W light bulb in circuit) and will likely overheat the ballast. I have burnt up several wall transformers by trying to run them on a triac device. Got hot enough to melt the case before the internal fuse link opened which stopped the probable house fire.
I do run a four tube ceiling fixture from a W467. But the WS467 powers a 60W bulb in parallel with a 120V coil relay. The relay contacts then put a closure across the original wall switch. Of course if I flip the wall switch ON, the relay loses all control of the light. The relay coil ias such a small load that it is not affected by the distorted waveform. The bulb helps smooth the waveform for the coil, but also provides the needed trickle current for the WS467. I got a 120VAC coil DPDT relay from either Radio Shark or "All Electronics". This is all in an unfinshed part of the basement and I just mounted the WS467bulb socket and relay is a double wall box nailed to a stud. Before putting this Rube Goldberg affair in service I did a burn-in test of the WS467, light bulb, and relay for several days to be sure the relay coil did not get warm.
