I just grabbed a used 2 speed motor
I want to use it on my Buffalo 15 upright DP, should help slow it down for use when drilling metal.
Pic of wiring attached below, but my question is what kind of AC switch can I use for this application?
DC I'd use a SPDT, but for this I have no idea.

Yes I know it may be under powered @ 1/2 speed (bout 1/3hp)... if it doesn't work out I have other possible uses for it.

thanks

Same as DC in this case.
Just use any 3 way light switch, which is a SPDT switch in reality. If this is also your ON/OFF in addition to HI/LOW than you will need a center off toggle that can handle the current.

Me, I would get a drum switch to stay in the vintage look. Any spdt center off motor rated switch will work though.

Used a similar two speed motor on my wood lathe, and used 15Amp a SPDT toggle switch for the Hi/low sequence. The other switch (DPDT) is for F/Rev. The Décor switch is the main shut-off.

shows my lack of knowledge re:AC switches, I didn't know they had SPDT options.
Will have to track one down
Ideally this will be the on/off switch, but I could actually used independent on/off & hi/low switches for each task.

thanks folks
