Defroster switches..

["adam_one_million" <acprice1@xxxx>]

My defroster switch has been broken since I've had my car so i dont 
know what the correct operation for this switch is. Does this switch 
stay in the "on" position until pressed back into the "off" position? 
Or does it spring back like the window switches? I am wondering 
because I may buy a new one to use as an auxilary switch for the 
cooling fans.

thanks,
adam
