	The one closes and opens its contacts in a vacuum. The other does it in air. "It does exactly what it says on the tin." __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	The reason for breaking contacts in a vacuum is to control or eliminate the arc, if that;s helpful. __________________ I do not 'know it all', but i will admit that I would like to. CJM
