 267 forum posts | I think this may be same as the Dewherst switch. If it is I can help. The Dewherst has 8 terminals , 4 on each side. Switch is operated by 4 position lever with round knob , off , forwards, off, reverse. D shape when veiwed from the top. |

I expect the switch to be a "cam" switch
made from a stack of sections
comprising of two single pole swiches that make on alternate positions
depending on the version , a link may be allready installed
linking both switches to form a single pole double throw switch
 the net result the swich can be wired as a two pole double throw switch
you can use to swop two of the phases on a three phase motor
or the connections to one of the windings on a single phase motor
hope the pictures help
John

extra diagrams for forward stop and reverse control
with cam switches and drum switches
I'm sure one should match your switch ?

| 10 forum posts | Hi John i will print these off and thankyou very much for your help, it hasnt helped having obscure motors with no diagrams as to start/run windings etc, however i have got it up and running on a Dewhurst i have spare, (i cant really see much point in running a lathe in reverse, unless we are staking bets on how long before the chuck flies OFF). Once again many thanks, its things like this that refresh my loving the net!! Kind Regards Paul. |

| 1294 forum posts 108 photos 1 articles | Actually a good reverse is very handy, in the right situations. I have a Newton Tesla controller on mine, and use the reverse instead of trying to get the screwcutting indicator right. The AC motor controllers are good because they have a controlled slow acceleration, so they don't tend to make the chuck unscrew from inertia. You can go slow forward while cutting, so you don't overrun the end, and go back fast to save time. But if course not quite as cheap as a simple switch! regards John |

318 forum posts 183 photos |  Hi Paul , just spotted an error on the last picture
the top diagram , in the forward direction two of the phases are short circuited
to reverse your motor you can reverse the connections to any one of the windings
while the diagrams show the start winding connections being reversed
you can switch the run winding if it is easier
