Will this switch work?

[skippyelwell]

I have a linear motor to power the table on my drill press.
The motor has 3 wires coming from it, blue is fwd, black is rev, white is common with start capacitor going to the blue/blk wires.
I'm wondering I can use a momentary fwd-off-rev switch like the drawing below to activate it?
Thanks,

How much power is involved? What happens when you flip the switch into reverse when its running forwards? I would look at a contactor instead of a switch if theres any significant current involved.

Not much in the way of specs, 120vac, 1/12th of a HP, it was used on a treadmill.

I am not familiar with your motor wiring colors. Most I have seen have blue, red, black with the capacitor between red-black. I think the only difference really is that the white wire is there and the blue has replaced the red. So it should work.

I have used a common 3 way switch for direction. It worked but it still needed an spst switch for power. If your dpdt switch has an off center then it should work. I ran in to some really cost affective little switches on amazon. I got one for my drill press for this very thing. I like the rotary switch over just a toggle.

Switch will work but not the way you have it wired.

Capacitor goes to blue and black, connecting blue or black to line with the other wire open reverses the motor. Centre-Off SPDT or DPDT switch will work just fine.

(Green isn't ground, but it's impossible to draw a white wire.

@whydontu , so you're saying the white wire is a ground? I wish they could come to some worldwide consensus on the colour of grounding wires.
Thanks
@djberta , that is a nice little switch, usually rotary switches start at $100. I found the same switch on Ali for $9

@skippyelwell see my post in your other thread on this motor I sent. But the guys above have told you the same thing I posted.

Never mind, I see what you are saying, white is white, understood.
