I was also told that sparks can occur depending on what part of the wave form at the time of switching

Dont know how true it is, i think it was told to me by an old college lecturer many years ago

 
Every now and again a socket and a light switch in my garage spark when flicking the switch, does anybody know why this would happen?
Come on guys ...... headbang

It depends where you are in the sine wave when you flick the switch which of course you don't know. But if it's at the top then you are switching maximum current hence the spark.

Cheers, Ron

I tend to think you are breaking the contact for more than 1/50th of a second so won't make a bit of difference in practice....
