opus - Good point, I swear I didn’t see your post prior to my spewing of differentials. Ignore the above.

Well, I guess my grandpa, being dead these past twenty-seven years, ain’t got much to say.

On his behalf, I’ll say that he didn’t have much schooling in anything. Electronics was a thing as alien to him as Mandarin Chinese is to almost everyone who reads this.

My grandpa called that can strapped to or near a refrigerator motor a “coil.” Many others I’ve known have done so. You, sir, can call it anything you like, but you, like most of the folks who knew my grandpa, know EXACTLY what he was talking about.

If my refrigerator took a shit, I’d look around, I’d see you, and I’d start wishing my grandpa was still kickin’…

joemill \*\*\*\*\*\*\*\*\*\*\*\*snoflakes If you evercome back to this site here is your answer Draw 2 parrallel lines  
Thats a road Label 1 line N  
Label 2nd line S  
now draw a offramp from n to s  
that is a light bulb it could be a radio who cares now draw a stoplight somewhere on the offramp. that is your switch it doesn’t matter where the switch is it breaks the flow of current -cars- when it is turned off.  
Now do it again draw the same circuit.only this time use a tv set who cares it is your circuit.  
keep doing it til you draw enough current to burn the whole thing up .that is another lesson good luck.  
\*\*\*\*\*\*\*\*\*\*\*\*watch out for those snowflakes

Thanks everyone for your explinations. I was always under the assumption that ALL the electricity would go through the first circuit and there would be none left for the rest.

An interesting sideline. We all know that electricity travels around the speed of light. But I heard that if you could tag an individual electron and watch it jump from atom to atom in an electrical circuit, it moves amazingly slow (something like 1 foot an hour). Heard that on a science program…

Upon further consideration  
You may be talking about using a 2way switch like used in the home stairwell.They run a wire between the switches and switch the hot side back and forth.It is easiest to understand by looking at the box that the switch comes in . The wiring diagram is self explanitary Try Walmart Menards Lows etc
