HOW?

How does closing a relay wether it is a hot closure or not produce a 
transient in anode current?

I always thought anode current (other than bias current) was produce by a 
driving signal.  Hot switching is not good, but I don't think it is a 
cause of anode current transients.  I fail to see the connection (no pun 
intended!).
