Thanks Wild Bill,

I've got it figured out now. For future reference if anyone else is
having a similar problem feel free to e-mail me and I can send you a
wiring diagram for this type of situation.

The thermal protection device has two leads, and is probably a Klixon-type
which is capable of carrying the motor start/run current.
In the event that the TP device isn't rated for the motor switching current,
don't use it for an AC line voltage protection device. A TP device can be
intended for controlling a relay coil, but most TP devices that are used in
single phase AC motors are capable of carrying the motor current.

You treat one lead of the TP device as a line connection, and the other lead
goes to the motor's line connection, (in series with the motor lead, the TP
opens if the motor temperature reaches the TP cutout temp).

Be aware that TP devices are often the self-resetting type (typically, there
is no external manual reset button.. push to reset), and the motor will be
re-energized when the motor cools down to the TP reset temp.

Thanks Grant,

That page cleared up alot. It appears I was just bipassing the start
capacitor circut altogether in the off mode. Problem is my motor has
thermal protection so it has 7 leads, not 6..... I could bipass it but
I'd like to keep it if its possible to wire the switch with thermal
protection. Any ideas here?

Hey guys,

I just bought a Furnas R327A forward...stop....reverse drum switch
for the motor on my Lathe. I'm running a Leeson 115V single phase
motor. I'm having a bit of trouble wiring the switch though. I've
posted a pdf diagram here

http://home.comcast.net/~dan-jill/

to illustrate the wiring of the motor and what I've tried. The advice
of anybody with any experience at this would be much appreciated.

Thanks

Dan Miller
