I have a DP-350 bench top drill press that has a broken switch (it
fried and smoked). I have a new one on the way, but I pulled the
wires off it w/o writing down how they go back.

Anyone mind taking a look at theirs? It pulls forward by removing
three scews.

I would call Delta, but I'm sure I will have to jump through 2,000
hoops to get the answer.

Thanks

You have been provided with a great opportunity.

If you don't have one, now is the time to trot down to your local
Radio Shack and buy an inexpensive VOM.

No shop should be without one, IMHO.

About $10.00 for an analog one.

Maybe $30-$40 for a digital one.

When you have one, walking you thru installing the new switch will be
a piece of cake.

I had the switch go bad my self. and they sent me one. As for the wires, I
don't remember the colors, but do you have a test light or ohm meter? I
would check continuity from the plug (removed from the outlet) to the wires.
Once you find which are the power wires, put those on one side of the
switch, and the motor to the other.

I know which pair of wires are on the 'Off' side and which pair go to
the 'On' side of the switch, but I don't know left-right for each
pair. Black on left or white on left?
I guess this is a good time to learn how to use an ohm meter.

thanks.

Lew,

As it turns out, I have an ohm meter (I wasn't sure if the meter I
have measures ohm's, but it does).

I have four (actually six, but two are a set of two) wires. Two goto
the off side and two goto the on side of the switch. I know which
pair goes where, but I don't know the polarity. White-black on which
side?? How do I determine this or does it not matter in a switch of
this type?

Let me guess.

This is probably a 115VAC machine.

Delta has probably standardized on a single switch for both their
115VAC and 230VAC machines to minimize inventory which is NBD.

When you get the new switch, test it for continuity with your VOM.

My guess is that it will have four(4) terminals, 2 on each side.

Put the switch in the "ON" position, then test for contunity till you
find the pairs that show conductivity.

One pair will be for "Black", the other pair will be for "White".

After you install new switch, but before you plug it back in, turn
switch "OFF" and test for contunitity at the plug.

It should show "Open".

Flip switch, test again.

It should show "Closed".

Have fun.

Yes. The switch has four terminals. When it arrives I will run
through what you suggested. This will be the first time I have used
the ohm portion of the meter (I usually use it for measuring
voltage). Thanks for your help!!

It does not matter which side of the switch you put the pairs. A switch
simply opens and closes a circuit. You can put your black on which ever
side you think looks nicer.

This parts drawing has the wiring diagram:

This may help. Place the black/colored/hot wire on the brass
screw terminals. The white/neutral wire goes on the silver
terminals if so provided. Green and bare are interchangeable for
ground.
